Verdict

Safe to feed

The details

Broccoli florets and stems provide fiber, vitamin C, and vitamin K. Chickens will pick at both raw and cooked broccoli, and a hung head keeps a bored flock busy.

How to serve it

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

Treat rules that apply to everything

Whatever you're feeding, the 90/10 rule is the one to remember: at least 90% of a hen's intake should be balanced layer feed, and no more than about 10% treats and scraps. Layer feed is formulated to deliver the protein and calcium that eggshells and feathers are built from — pile on the treats and you dilute it, which shows up as thin shells and a slowed-down lay.

That is a stricter limit than it sounds. Ten percent of a dozen hens' daily feed is only about 4.8 oz of treats — for all twelve birds combined, not each. Work out the limit for your own flock with the chicken treat calculator.

Chickens have no teeth: they grind food in the gizzard using grit. Birds that free-range pick up their own, but a confined flock needs insoluble grit available whenever they eat anything beyond feed. Introduce any new food in a small amount and watch the flock for a day — droppings are the quickest tell that something didn't agree with them.

Two rules that override everything else: never feed anything mouldy, since some moulds produce mycotoxins that can kill a bird, and never feed heavily salted, sugary, or processed human food. If you wouldn't eat it, it doesn't go in the run.

Frequently asked questions

Can chickens eat broccoli?
Yes — broccoli, raw or cooked, is a safe and vitamin-rich treat. Broccoli florets and stems provide fiber, vitamin C, and vitamin K. Chickens will pick at both raw and cooked broccoli, and a hung head keeps a bored flock busy.
How should I feed broccoli to chickens?
Offer raw or steamed broccoli a few times a week. Remove any that goes slimy.
Can baby chicks eat broccoli?
Yes, in small amounts, once chicks are around two weeks old. Treats should still be a tiny fraction of their diet, and chicks need chick-size grit to grind anything other than starter feed.
How much of a chicken's diet can treats be?
Follow the 90/10 rule: at least 90% of what a chicken eats should be balanced layer feed, with treats and kitchen scraps making up no more than about 10%. The feed carries the protein, calcium, and micronutrients that keep hens laying — treats dilute all of that if they take over.
