What Can Chickens Eat?

Chickens are omnivores and will try almost anything — but a handful of common foods are genuinely toxic. Here's a sourced verdict on 91 foods people ask about most.

Reviewed against extension and veterinary guidance · Last reviewed August 2026

Never feed these

alcohol, avocado, bacon, candy, chocolate, coffee grounds, french fries, moldy food, onions, rhubarb, salty foods, tea — plus anything mouldy, alcoholic, caffeinated, or heavily salted.

These aren't "probably fine in small amounts" foods. Avocado and chocolate in particular can kill a bird outright.

Garden and hedgerow plants are a separate list — see plants toxic to chickens.

Fruit

Sweet and watery. Sugar is usually the limit here rather than toxicity — the exceptions are avocado, and the pits and seeds of stone fruit.

apples

Safe to feed

Yes — apple flesh is a great treat; just skip the seeds.

Serving: Chop apple into pieces and remove the core and seeds. Offer a few times a week.

Nutrition: Fibre and vitamin C, in both the flesh and the skin.

⚠️ Caution: Seeds contain amygdalin (a cyanide compound) — remove the core before feeding.

🚫 Avoid: The core and its seed pocket.

avocado

Do not feed

No — avocado contains persin and is one of the most dangerous foods for chickens.

Serving: Never feed any part of an avocado, and don't compost the skins or pits where the flock can reach them.

Nutrition: Beside the point — the persin risk overrides any nutritional value it has.

⚠️ Caution: Persin (in skin, pit, leaves, and flesh) can cause fatal heart failure in birds. Never feed.

🚫 Avoid: Every part, including skins and pits in an open compost heap.

bananas

In moderation

In moderation — banana flesh is safe and nutritious but high in sugar.

Serving: Offer a few slices of peeled banana once or twice a week, mashed or in chunks.

Nutrition: Potassium, vitamin B6 and vitamin C, alongside a lot of natural sugar.

🚫 Avoid: The peel — not toxic, but tough and a common pesticide-residue carrier.

blackberries

Safe to feed

Yes — blackberries are safe, and a flock ranging near a hedgerow will find them without any help.

Serving: Offer a handful of picked berries, or simply let a ranging flock work a hedge you know has not been sprayed.

Nutrition: Antioxidants, vitamin C, vitamin K and a good deal of fibre.

🚫 Avoid: Berries from sprayed roadside or field-margin brambles.

blueberries

Safe to feed

Yes — blueberries are a nutrient-dense, chicken-safe favorite.

Serving: Scatter a small handful per few birds as an occasional treat. No need to cut them.

Nutrition: Unusually dense in antioxidants for their size, plus vitamins C and K.

cantaloupe

Safe to feed

Yes — cantaloupe and other soft melons are safe right through, seeds and rind included.

Serving: Set out the scooped-out seedy centre and the rind after you have cut a melon up. Chunks work too.

Nutrition: Water, vitamin A and vitamin C, with a little more substance than watermelon.

cherries

Safe to feed

Yes — cherry flesh is a safe treat once you remove the pits.

Serving: Pit the cherries and offer the flesh, whole or chopped, as an occasional treat.

Nutrition: Antioxidants plus vitamins A and C.

⚠️ Caution: Pits, stems, and leaves contain cyanide compounds — feed pitted flesh only.

🚫 Avoid: Pits, stems and leaves.

coconut

In moderation

In moderation — coconut flesh is safe and well liked, but it is unusually high in fat.

Serving: Set out a cracked half-shell for the flock to peck out, occasionally. Keep desiccated coconut plain and unsweetened.

Nutrition: Fat above all, plus fibre, manganese and a little protein.

🚫 Avoid: Sweetened desiccated coconut, and the hard shell itself.

cranberries

Safe to feed

Yes — cranberries are safe and antioxidant-rich, though plenty of flocks find them too sour to bother with.

Serving: Scatter a few fresh or thawed cranberries and see whether your birds take to them. Halve them for smaller hens.

Nutrition: Antioxidants and vitamin C, with very little sugar by fruit standards.

🚫 Avoid: Dried sweetened cranberries, and anything from a sauce or jelly.

figs

Safe to feed

Yes — fresh figs are safe and enormously popular, though the sugar keeps them occasional.

Serving: Halve fresh figs and offer one between a few birds occasionally. Dried figs want chopping and rationing harder still.

Nutrition: Fibre, calcium and potassium, with sugar high enough to be the limiting factor.

grapes

In moderation

In moderation — grapes are a beloved treat but sugary and a choking risk whole.

Serving: Halve grapes and offer just a few per bird as an occasional treat.

Nutrition: Vitamins and antioxidants, with a high sugar load for the size of the mouthful.

⚠️ Caution: Whole grapes can choke a greedy hen — halve them, and keep portions small due to sugar.

kiwi

Safe to feed

Yes — kiwi flesh, seeds and even the fuzzy skin are all safe.

Serving: Halve a kiwi and let the birds scoop it out, or peel and dice it. An occasional treat rather than a staple.

Nutrition: More vitamin C by weight than an orange, plus vitamin K and potassium.

lemons

In moderation

In moderation — lemons are not toxic, but they are sharp enough that most flocks refuse them outright.

Serving: If you want to try, offer a small piece of flesh and see what happens. Most keepers conclude it is not worth the bother.

Nutrition: Vitamin C, in about the most acidic form a chicken will ever be offered.

mango

Safe to feed

Yes — mango flesh is a safe and very popular treat once the big stone is removed.

Serving: Cut the flesh off the stone, dice it, and offer a small amount occasionally. The skin is safe but often left.

Nutrition: Vitamin A and vitamin C in quantity, alongside a lot of sugar.

oranges

In moderation

In moderation — oranges are not toxic despite the folklore, but the acidity means small amounts only.

Serving: Offer a few segments occasionally and see if your flock takes to them. Remove uneaten pieces before they spoil.

Nutrition: Vitamin C, in an acidic package many flocks simply refuse.

peaches

Safe to feed

Yes — peach flesh is a good treat once the stone is out of the way.

Serving: Stone the fruit, chop it into pieces, and offer a few times a week. Bruised windfalls are ideal.

Nutrition: Vitamins A and C plus fibre, in a fruit that is largely water and sugar.

🚫 Avoid: The stone, and any fruit that has begun to ferment.

pears

Safe to feed

Yes — pear flesh and skin are both fine; treat the core the way you would an apple core.

Serving: Core the pear, chop the flesh, and offer it a few times a week. Overripe fruit is fine as long as it is not fermenting.

Nutrition: Fibre and vitamin C, with a higher sugar load than an apple.

🚫 Avoid: The core and its seeds.

pineapple

In moderation

In moderation — pineapple flesh is safe but acidic and fibrous, so it is an occasional treat at best.

Serving: Offer small chopped pieces of ripe flesh occasionally, cut across the grain so the fibres come apart. Skip the core.

Nutrition: Vitamin C and manganese, delivered with a lot of acid and a lot of sugar.

🚫 Avoid: The woody central core, and anything tinned in syrup.

plums

Safe to feed

Yes — plum flesh is safe, but the stones need to come out before the fruit goes anywhere near the run.

Serving: Stone plums and halve them before offering. If a tree overhangs the run, pick up windfalls daily rather than trusting the flock to spit out the stones.

Nutrition: Vitamin C, vitamin K and fibre, in a notably sugary package.

🚫 Avoid: The stones, and windfalls that have started to ferment.

pomegranate

Safe to feed

Yes — pomegranate seeds are safe and make an unusually entertaining treat.

Serving: Cut one in half and set it down cut-side up, or scatter loose arils. An occasional treat.

Nutrition: Antioxidants, vitamin C and vitamin K, in seeds that are mostly juice.

🚫 Avoid: The bitter white pith and the outer skin.

raisins

In moderation

In moderation — raisins are safe for chickens despite the dog warnings, but they are concentrated sugar.

Serving: Offer a few raisins per bird as a training or taming treat. Soaking them first makes them easier going.

Nutrition: Iron, potassium and fibre, concentrated alongside a great deal of sugar.

raspberries

Safe to feed

Yes — raspberries are a safe, soft-fruit favourite, and the canes are worth netting for that reason.

Serving: Scatter a small handful between a few birds. Berries that have gone soft are perfect, mouldy ones are not.

Nutrition: Fibre, vitamin C and antioxidants, in a soft berry that needs no preparation.

strawberries

Safe to feed

Yes — strawberries are a safe, vitamin-rich treat chickens go wild for.

Serving: Offer whole or halved berries a few times a week. Overripe berries from the garden are perfect for the flock.

Nutrition: Vitamin C, fibre and antioxidants, with the leafy tops safe as well.

tomatoes

Safe to feed

Yes — ripe tomato flesh is a healthy treat, but never the leaves, stems, or unripe green fruit.

Serving: Offer ripe, chopped tomato a few times a week. Keep birds out of the tomato patch so they can't nibble foliage or green fruit.

Nutrition: Vitamins A, C and K, plus the antioxidants that give a ripe tomato its colour.

⚠️ Caution: Leaves, vines, and green (unripe) tomatoes contain solanine — toxic. Only ripe flesh is safe.

🚫 Avoid: Leaves, stems, vines, and unripe green fruit.

watermelon

Safe to feed

Yes — watermelon is one of the best hot-weather treats, flesh, seeds, and rind all included.

Serving: Halve a chilled watermelon and set it out on a hot afternoon. Because it is mostly water and sugar, treat it as a snack, not a meal.

Nutrition: About 90% water with vitamins A and C — the value here is hydration far more than calories.

Vegetables

The largest group, and the one carrying most of the nightshade caveats: tomato, potato and pepper plants are all riskier than their fruit.

asparagus

In moderation

In moderation — asparagus is not harmful, but it is reported to taint egg flavour and most flocks ignore it.

Serving: Chop it small and cook it if you want to try, in small amounts. Clear away whatever is left rather than letting it sit.

Nutrition: Folate, vitamin K and fibre — perfectly respectable, if the birds will take it.

bell peppers

Safe to feed

Yes — the ripe fruit is safe, but bell peppers are nightshades and the plant itself is not.

Serving: Chop peppers, seeds and all, and offer a few times a week. Keep the flock out of the pepper bed itself.

Nutrition: A great deal of vitamin C, plus vitamin A in the red and orange ones.

🚫 Avoid: Leaves, stems and flowers of the plant.

broccoli

Safe to feed

Yes — broccoli, raw or cooked, is a safe and vitamin-rich treat.

Serving: Offer raw or steamed broccoli a few times a week. Remove any that goes slimy.

Nutrition: Fibre, vitamin C and vitamin K, in the florets and the stems alike.

brussels sprouts

Safe to feed

Yes — sprouts and their stalks are safe, and a flock is usually keener on them than the family is.

Serving: Halve raw sprouts or offer them lightly cooked, a few times a week. The bare stalk makes a serviceable pecking toy.

Nutrition: Vitamin C, vitamin K and fibre, in a dense little package.

cabbage

Safe to feed

Yes — cabbage is safe and doubles as a winter boredom-buster.

Serving: Hang a whole head at head height, or offer chopped leaves. Fine several times a week.

Nutrition: Vitamins C and K plus fibre.

carrots

Safe to feed

Yes — carrots and their tops are both safe and healthy.

Serving: Grate raw carrot or offer cooked chunks a few times a week. Chop the tops finely.

Nutrition: Beta-carotene, which deepens yolk colour, plus fibre and vitamins.

cauliflower

Safe to feed

Yes — cauliflower florets, stalk and leaves are all safe, raw or cooked.

Serving: Hang a head, or offer chopped florets and the outer leaves raw or steamed, several times a week.

Nutrition: Vitamin C, vitamin K and fibre.

celery

Safe to feed

Yes — celery is safe, though the stringy fibres are worth cutting up before they cause trouble.

Serving: Chop celery across the stalk into short pieces so the strings come apart, and offer the leaves whole.

Nutrition: Mostly water, with modest vitamin K and potassium; the leaves beat the stalks.

cucumber

Safe to feed

Yes — cucumber is a hydrating, low-calorie treat, seeds and all.

Serving: Halve a cucumber lengthwise and let the flock scoop out the middle, or offer chopped chunks.

Nutrition: Mostly water, with modest vitamins and minerals — a hydration treat.

garlic

In moderation

In moderation — small amounts are widely fed and well tolerated, but garlic is an allium, like onion.

Serving: A crushed clove or two per gallon of water, or a little chopped into feed — occasionally, not daily.

Nutrition: Trace minerals and sulphur compounds; nothing a balanced feed does not already supply.

⚠️ Caution: An allium, like onion — small amounts only, and never as a substitute for veterinary treatment.

green beans

Only when prepared

Only cooked — raw green beans carry the same lectin that makes dried beans dangerous, at a lower dose.

Serving: Steam or boil green beans through before offering them, then chop into short lengths. Nothing salted or buttered.

Nutrition: Fibre, vitamin K and vitamin C once cooked.

⚠️ Caution: Raw green beans contain phytohaemagglutinin, the same lectin as dried beans. Cook thoroughly first.

kale

Safe to feed

Yes — kale is one of the most nutritious greens you can offer a flock.

Serving: Offer torn leaves several times a week, or hang a whole stalk as a winter boredom-buster.

Nutrition: Vitamins A, C and K plus calcium — about as nutrient-dense as greens get.

lettuce

Safe to feed

Yes — leafy lettuce is a healthy green, though skip watery iceberg in quantity.

Serving: Offer torn leaves daily if you like; hang a whole head to give the flock something to peck at.

Nutrition: Hydration plus vitamins A and K — far more of both in the darker leaves.

mushrooms

In moderation

In moderation — shop-bought culinary mushrooms are safe, but never let a flock forage wild ones.

Serving: Offer chopped shop-bought mushrooms occasionally. More usefully, walk the run in autumn and kick over anything that has come up.

Nutrition: B vitamins, selenium and a little protein, in something that is mostly water.

⚠️ Caution: Culinary mushrooms only. Wild mushrooms include lethally toxic species — never let the flock forage them.

onions

Do not feed

Best avoided — onions contain thiosulphate, which in any real quantity can cause anemia.

Serving: Don't feed onions as a treat. Keep them out of the scrap bowl you share with the flock.

Nutrition: Not worth counting — the thiosulphate risk is the entire story here.

⚠️ Caution: Thiosulphate damages red blood cells — regular or large amounts cause anemia. Avoid feeding.

peas

Safe to feed

Yes — fresh, frozen or cooked peas are one of the better vegetable protein sources you can offer.

Serving: Scatter a small handful of thawed frozen peas, or offer fresh pods. Fine several times a week.

Nutrition: More protein than most vegetables, plus vitamins A, C and K and useful fibre.

potatoes

Only when prepared

Only cooked — plain cooked potato is fine, but raw, green, or sprouted potato and peels are toxic.

Serving: Feed only plain cooked potato flesh with no green. Skip the peels, and never offer raw or sprouting potatoes.

Nutrition: Starch and a little vitamin C once cooked — filling rather than nourishing.

⚠️ Caution: Raw, green, and sprouted potato plus peels contain solanine — toxic. Cook first, discard green parts.

🚫 Avoid: Raw potato, green skin, sprouts and peels.

pumpkin

Safe to feed

Yes — pumpkin flesh and seeds are a nutritious autumn favorite.

Serving: Cut a pumpkin open and let the flock work at the flesh and seeds. Leftover Halloween pumpkins are perfect if not painted or rotten.

Nutrition: Vitamin A, fibre and antioxidants in the flesh; fat and protein in the seeds.

🚫 Avoid: Anything painted, glittered, waxed, or already going soft.

rhubarb

Do not feed

No — rhubarb, especially the leaves, contains oxalic acid at toxic levels.

Serving: Never feed rhubarb leaves, and keep the flock out of the rhubarb patch.

Nutrition: None that counts for anything against the oxalic acid load.

⚠️ Caution: Leaves contain toxic levels of oxalic acid — can cause kidney damage and death. Never feed.

🚫 Avoid: The leaves above all — but do not offer the stalks either.

spinach

In moderation

In moderation — spinach is nutritious but its oxalic acid can interfere with calcium.

Serving: Offer a small amount of raw or cooked spinach once or twice a week, not daily.

Nutrition: Iron and vitamins A, C and K — undercut by oxalic acid that binds calcium.

⚠️ Caution: Oxalic acid binds calcium — too much can affect eggshell quality. Feed occasionally.

sweet potatoes

Safe to feed

Yes — sweet potatoes are safe raw or cooked, unlike regular potatoes.

Serving: Offer cooked mash or chunks, or raw grated sweet potato, a couple of times a week.

Nutrition: Vitamin A in quantity, plus fibre — in the flesh, the skin and the vines alike.

winter squash

Safe to feed

Yes — butternut, acorn and other winter squash are safe, flesh and seeds alike.

Serving: Halve or quarter a squash and set it out, seeds and all. Roasting the flesh makes it easier going for older birds.

Nutrition: Vitamin A and fibre in the flesh, with fat and protein in the seeds.

zucchini

Safe to feed

Yes — zucchini and other summer squash are safe whole: flesh, skin and seeds together.

Serving: Halve one lengthwise and let the flock hollow it out, or offer it grated or chopped into chunks.

Nutrition: Mostly water, with vitamin C, some vitamin A and a little potassium.

Garden & foraged

Weeds, herbs and forage a ranging flock will find whether or not you offer it — so the verdict has to account for what birds do unsupervised.

basil

Safe to feed

Yes — basil is safe, though most flocks are noticeably unenthusiastic about it.

Serving: Toss in bolted or frost-damaged plants and see whether your flock takes any interest.

Nutrition: Vitamin K and aromatic oils; a trace contributor rather than a real food.

cilantro

Safe to feed

Yes — cilantro is safe, and a bolted plant is more use to the flock than to the kitchen.

Serving: Pull bolted plants whole and toss them in, or offer cut leaves. Stems and seed heads are fine too.

Nutrition: Vitamins A, C and K, plus potassium — respectable for a soft herb.

clover

Safe to feed

Yes — clover is safe, high in protein for a forage plant, and worth deliberately sowing in a run.

Serving: Let the flock graze it. If you are seeding a run or a rotation paddock, clover is worth including in the mix.

Nutrition: Notably high protein for a green, plus calcium and a range of trace minerals.

dandelions

Safe to feed

Yes — dandelions are edible root to flower and are one of the best free greens available.

Serving: Pull whole plants and toss them in, or simply let the flock work over an untreated lawn.

Nutrition: Vitamins A, C and K, calcium and iron — genuinely nutrient-dense for a weed.

🚫 Avoid: Anything from a lawn treated with herbicide or weed-and-feed.

grass clippings

In moderation

In moderation — short fresh clippings are fine, but a pile of long mower cuttings can impact a crop.

Serving: Let birds graze living grass freely. If you tip clippings in, use short cuttings only, spread thin, and never a warm heap straight off the mower.

Nutrition: Fibre and chlorophyll, plus whatever the lawn itself is worth — modest either way.

⚠️ Caution: Long mower clippings are a crop-impaction risk, and treated lawns carry herbicide residue.

🚫 Avoid: Long strands, warm fermenting heaps, and clippings from any lawn that has been treated.

marigold

Safe to feed

Yes — marigold petals are safe, and they are the reason some commercial yolks are so orange.

Serving: Let birds pick at the flowers, or scatter petals into feed. Deadheaded flowers are ideal.

Nutrition: Xanthophylls — the carotenoid pigments that deepen yolk colour — plus trace vitamins.

mint

Safe to feed

Yes — mint is safe, grows faster than a flock can eat it, and is a traditional coop herb.

Serving: Let it grow where birds can reach it, or scatter cut sprigs in the coop and nest boxes.

Nutrition: Trace vitamins and aromatic oils; a flavour and freshening plant more than a food.

nasturtium

Safe to feed

Yes — leaves, flowers and seed pods are all safe, and it is a long-standing poultry-yard plant.

Serving: Grow it where the birds can reach it, or cut and offer leaves and flowers. Nothing needs preparing.

Nutrition: Vitamin C and peppery mustard oils, in a plant that is edible from top to bottom.

nettles

Only when prepared

Only wilted, dried or cooked — nettles are excellent flock food once the sting is gone.

Serving: Cut nettles and leave them to wilt for a day, or dry and crumble them into feed. Cooked nettles work too.

Nutrition: Exceptionally high in protein for a wild green, plus iron, calcium and vitamins A and C.

⚠️ Caution: Never feed fresh standing nettles — wilt, dry or cook them first to destroy the sting.

oregano

Safe to feed

Yes — oregano is safe, and it is the herb with the most actual poultry research behind it.

Serving: Let it grow within reach, or crumble dried oregano into feed. Both are fine as a routine.

Nutrition: Aromatic compounds including carvacrol and thymol; negligible as calories.

parsley

Safe to feed

Yes — parsley is safe, nutritious, and one of the herbs flocks actually finish.

Serving: Offer whole bunches or let the flock strip a plant. Fine several times a week.

Nutrition: A great deal of vitamin K, plus vitamins A and C and useful iron.

Grains & pantry

Cheap, filling and easy to overdo. Most of these dilute a balanced feed rather than adding anything to it.

barley

Safe to feed

Yes — barley is a safe grain, and sprouting it turns a cheap sack into winter greens.

Serving: Scatter whole or rolled barley as a scratch grain, or sprout it into fodder for a winter flock.

Nutrition: Carbohydrate with more fibre and protein than corn, plus B vitamins.

bread

In moderation

In moderation — a little bread is a harmless treat, but it is empty calories and moldy bread is dangerous.

Serving: Offer only small amounts of fresh, plain bread occasionally. Never feed moldy bread.

Nutrition: Starch and very little else — calories that displace balanced feed.

⚠️ Caution: Moldy bread can carry mycotoxins that are dangerous to chickens — feed only fresh, and sparingly.

🚫 Avoid: Anything showing mould, and heavily salted or sweetened loaves.

breakfast cereal

In moderation

In moderation — plain unsweetened cereal is a harmless treat, but most boxes are largely sugar.

Serving: Offer a small handful of plain unsweetened cereal as a taming treat. Read the sugar content before the flock does.

Nutrition: Refined grain, and in most boxes a great deal of added sugar.

🚫 Avoid: Frosted, honeyed, chocolate and marshmallow varieties.

corn

Safe to feed

Yes — corn is a flock favorite, best fed as an energy treat rather than a staple.

Serving: Offer corn on the cob, or a scatter of kernels, as a treat rather than the main meal.

Nutrition: High energy and low protein — calorie-dense, and not balanced on its own.

crackers

In moderation

In moderation — a plain cracker will not hurt a hen, but salt is the reason to keep the packet shut.

Serving: Crumble half a plain unsalted cracker between several birds, rarely. Salted, seasoned and cheese-flavoured varieties stay indoors.

Nutrition: Refined starch and salt; nothing that a chicken has any nutritional need for.

🚫 Avoid: Salted, seasoned, flavoured and cheese-topped varieties.

flax seeds

In moderation

In moderation — flax is how omega-3 enriched eggs are produced, but it has a sensible ceiling.

Serving: Mix a small amount of ground or whole flax into feed rather than offering it alone. Keep it well under a tenth of what they eat.

Nutrition: The richest plant source of omega-3 on this list, plus fibre and protein.

oats

Safe to feed

Yes — oats and plain oatmeal are a wholesome, warming treat.

Serving: Offer dry rolled oats or plain (unsweetened) cooked oatmeal a few times a week.

Nutrition: Fibre, protein and B vitamins.

pasta

In moderation

In moderation — plain cooked pasta is a harmless treat, but it is starch and very little else.

Serving: Offer a small amount of plain cooked pasta, rinsed of any sauce, now and then. Chop long shapes so nobody runs off trailing one.

Nutrition: Starch, with a little protein in wheat pasta — filling rather than nourishing.

🚫 Avoid: Anything sauced, salted, buttered or cheesy.

quinoa

Safe to feed

Yes — cooked quinoa is safe and carries more protein than most grains a flock will see.

Serving: Offer cooked, cooled, unsalted quinoa a couple of times a week. Rinse it before cooking, as you would for yourself.

Nutrition: A complete protein, unusually for a grain, plus magnesium, iron and fibre.

rice

Safe to feed

Yes — cooked or uncooked rice is safe; the "raw rice kills birds" claim is a myth.

Serving: Offer plain cooked or uncooked rice as an occasional treat. Skip heavily salted or seasoned rice dishes.

Nutrition: Carbohydrate; brown rice adds a little fibre and B vitamins over white.

sunflower seeds

Safe to feed

Yes — black oil sunflower seeds are a classic molt treat, rich in fat and protein.

Serving: Scatter a small handful between several birds, more freely during a molt and sparingly outside it.

Nutrition: High fat and protein, plus vitamin E and the amino acids feathers are built from.

Protein & dairy

The best molt-season treats are here, and so is most of the salt risk. Chickens are omnivores; they are just poor at handling dairy.

bacon

Do not feed

No — cured and processed meats carry far more salt than a chicken can handle.

Serving: Keep cured and processed meat out of the scrap bowl. Plain cooked unsalted meat is the version worth offering.

Nutrition: Protein and fat, buried under a quantity of salt that makes the rest academic.

⚠️ Caution: Curing salt and nitrates at preservation levels, in an animal that tolerates sodium poorly.

cheese

In moderation

In moderation — small amounts of cheese are fine, but chickens digest dairy poorly.

Serving: Offer occasional small crumbles of hard cheese. Avoid soft, very salty, or heavily processed cheese.

Nutrition: Protein, fat and calcium, in a form chickens are poorly equipped to digest.

⚠️ Caution: Chickens digest lactose poorly — too much dairy causes digestive upset. Keep portions tiny.

🚫 Avoid: Soft, very salty and heavily processed cheeses.

cooked meat

Safe to feed

Yes — chickens are omnivores, and plain cooked meat is about the highest-value protein treat there is.

Serving: Offer small pieces of plain cooked meat, trimmed of heavy fat, occasionally. No sauces, no salt, nothing cured or processed.

Nutrition: Complete protein and fat — the densest protein most flocks will ever be offered.

⚠️ Caution: Cooked and plain only — raw meat carries a bacterial risk, and cured or processed meat is far too salty.

dried or raw beans

Only when prepared

Only fully cooked — raw and dried beans contain a toxin that is deadly, but thorough cooking destroys it.

Serving: Feed only beans that have been soaked and fully cooked. Never offer raw or dried uncooked beans.

Nutrition: A good protein source once fully cooked — and genuinely deadly before that.

⚠️ Caution: Raw and dried beans contain phytohaemagglutinin — deadly. Only fully cooked beans are safe.

🚫 Avoid: Anything raw, dried-uncooked, or only partly cooked.

eggs

Safe to feed

Yes — cooked eggs are an excellent protein treat; just cook them first.

Serving: Offer scrambled or hard-boiled egg occasionally. Crush and dry the shells separately as a calcium source.

Nutrition: A near-complete protein — genuinely useful during molt or for a run-down bird.

⚠️ Caution: Feed only cooked eggs — raw eggs can trigger egg-eating behavior in the flock.

fish

Safe to feed

Yes — plain cooked fish is an excellent protein treat and one of the few good sources of omega-3.

Serving: Offer small amounts of plain cooked fish flaked off the bone. Nothing battered, smoked, salted or sitting in brine.

Nutrition: High-quality protein plus omega-3 fatty acids.

🚫 Avoid: Batter, brine, and smoked or heavily salted preparations.

mealworms

Safe to feed

Yes — mealworms are a protein-packed treat chickens treat like candy.

Serving: Offer a small pinch per bird, especially during molt. Buy mealworms labeled for poultry.

Nutrition: High protein and fat — which is exactly why they are a molt-season standby.

milk

In moderation

In moderation — a little milk will not hurt a chicken, but it is the form of dairy they cope with worst.

Serving: If you offer it at all, keep it to a splash over something else rather than a bowl on its own, and take it away before it sours in the sun.

Nutrition: Protein and calcium, delivered with more lactose than a chicken can comfortably process.

nuts

In moderation

In moderation — plain unsalted tree nuts are safe chopped, but they are rich and easy to overdo.

Serving: Chop plain unsalted nuts and offer a small scatter occasionally. Never salted, sugared, or from an old bag.

Nutrition: Protein, healthy fats and minerals, at a calorie density nothing else here matches.

⚠️ Caution: Mouldy nuts can carry aflatoxins, which poultry tolerate badly. Feed only fresh, plain, unsalted nuts.

🚫 Avoid: Salted and sugared nuts, shells, and anything stored long enough to smell musty.

peanut butter

In moderation

In moderation — plain peanut butter is safe, but check the label for xylitol and go easy on the texture.

Serving: Thin a small amount into feed, oats or seed rather than offering it neat. Choose a jar whose only ingredient is peanuts.

Nutrition: Concentrated protein and fat, and in most jars a fair amount of added sugar and salt.

⚠️ Caution: Check for xylitol, a sweetener that is dangerous to animals and appears in some reduced-sugar jars.

🚫 Avoid: Anything containing xylitol, and jars heavy with added salt or sugar.

peanuts

In moderation

In moderation — plain unsalted peanuts are a good protein treat, but mouldy ones are genuinely dangerous.

Serving: Offer a few plain unsalted peanuts per bird, chopped, as an occasional treat. Buy fresh stock and store it dry.

Nutrition: High protein and fat, plus vitamin E and B vitamins.

⚠️ Caution: Peanuts are a common aflatoxin carrier, and poultry are especially sensitive. Never feed mouldy or musty nuts.

🚫 Avoid: Salted, flavoured or coated peanuts, and absolutely anything musty or discoloured.

yogurt

In moderation

In moderation — plain yogurt goes down better than milk, but chickens still handle dairy poorly.

Serving: Offer a spoonful of plain yogurt between a few birds, occasionally rather than as a routine.

Nutrition: Protein, calcium and fat, carrying less lactose than milk thanks to fermentation.

⚠️ Caution: Plain and unsweetened only; flavoured yogurt is mostly sugar.

Snacks & kitchen extras

Processed human food. Very little in this group earns a place in a run, and the never-feed list is concentrated here.

alcohol

Do not feed

No — alcohol is toxic to chickens, and fermenting windfall fruit is how it usually happens by accident.

Serving: Never offer alcohol in any form, and clear fermenting windfalls out of the run rather than leaving them down.

Nutrition: None at all, and a direct toxic load on a very small liver.

⚠️ Caution: Ethanol is toxic and acts fast in a bird this size. Fermenting windfall fruit counts.

candy

Do not feed

No — sweets are pure sugar, may hide chocolate or xylitol, and offer a bird nothing whatsoever.

Serving: Do not feed sweets, chocolate, or sugar-free confectionery in any form, including the ends of baked goods.

Nutrition: Sugar, and in some cases compounds that are outright toxic.

⚠️ Caution: May contain chocolate or xylitol, both toxic. Even plain sugar confectionery is empty and sticky.

chocolate

Do not feed

No — chocolate is toxic to chickens and should never be fed.

Serving: Never feed chocolate or cocoa in any form. Keep baked goods containing it out of reach.

Nutrition: Nothing a chicken needs, and two compounds it cannot process.

⚠️ Caution: Contains theobromine and caffeine — toxic to the heart and nervous system. Never feed.

🚫 Avoid: All of it, including cocoa powder and any baked goods containing it.

coffee grounds

Do not feed

No — coffee grounds contain caffeine, the same toxic family as the theobromine in chocolate.

Serving: Never offer coffee grounds. Dig them into a bed or a closed bin rather than the open heap the flock can reach.

Nutrition: Nothing useful, plus a methylxanthine load birds cannot process.

⚠️ Caution: Caffeine is a methylxanthine, like the theobromine in chocolate — toxic to birds. Never feed.

french fries

Do not feed

No — fries combine salt, frying fat and empty starch, which is close to the worst possible combination.

Serving: Do not feed fries, crisps, or anything else out of a fryer. Plain cooked potato with no green on it is the version that is genuinely fine.

Nutrition: Fat and salt on a potato, with the potato's modest virtues fried out of it.

⚠️ Caution: Salt and frying fat. A human-sized portion is a substantial dose for a five-pound bird.

moldy food

Do not feed

No — mouldy food is the rule that overrides every other verdict on this site.

Serving: Feed nothing mouldy, musty, or that has been sitting damp. If you would not eat it yourself, it does not go in the run.

Nutrition: Beside the point: some moulds produce toxins that kill birds outright.

⚠️ Caution: Mycotoxins, aflatoxins especially, are potent and poultry are highly sensitive. Never feed anything mouldy.

popcorn

Safe to feed

Yes — plain popped popcorn is a fun treat; skip the salt and butter.

Serving: Offer a small handful of plain popped corn. No salt, butter, or sugar, and avoid unpopped kernels.

Nutrition: Essentially just corn — carbohydrate, and not much else.

⚠️ Caution: Salted, buttered, or caramel popcorn is not safe — offer plain, air-popped only.

🚫 Avoid: Unpopped kernels, and anything salted, buttered or caramel-coated.

salty foods

Do not feed

No — salt is the most underestimated hazard in a bowl of kitchen scraps.

Serving: Keep crisps, salted nuts, cured meat, anything tinned in brine, and seasoned leftovers out of the run entirely.

Nutrition: Sodium, in quantities calibrated for an animal thirty times a hen's size.

⚠️ Caution: Chickens tolerate sodium poorly, and salt toxicity is a documented cause of loss in poultry.

tea

Do not feed

No — tea carries caffeine too, and used bags on a compost heap are how a flock usually meets it.

Serving: Keep tea and used tea bags out of the run, and out of any compost heap the flock has access to.

Nutrition: Tannins and caffeine, and nothing a bird has any use for.

⚠️ Caution: Contains caffeine, a methylxanthine toxic to birds. Leave herbal infusions out too, as a default.

How treats fit into a chicken's diet

The single most useful rule is the 90/10 rule: at least 90% of what your flock eats should be balanced layer feed, with treats and kitchen scraps capped at roughly 10%. Layer feed is engineered to deliver the protein, calcium, and micronutrients that eggshells and feathers are made of. Treats are fun and useful for taming and boredom relief, but every handful of corn or bread displaces the feed doing the actual work — and that shows up as thinner shells and fewer eggs.

Ten percent is less than most people picture. A dozen hens eat about 3 lb of feed a day, so their entire treat budget is roughly 4.8 oz between them — not each. The chicken treat calculator turns the rule into a number for your flock size.

Chickens have no teeth. They grind everything in the gizzard using grit — small stones they swallow deliberately. Free-ranging birds find their own; a flock confined to a run needs insoluble grit on offer whenever they're eating anything other than feed. Skip it and even a perfectly safe treat can back up a crop.

Introduce anything new in small amounts and check the droppings the next day — that's the fastest signal something disagreed with them. And two rules that beat every list on this page:never feed mouldy food (some moulds produce mycotoxins that kill birds), and skip anything heavily salted, sugary, or processed. Chickens are small; a portion of salt that's trivial for you is not trivial for a 5 lb bird.
