Verdict

In moderation

The details

The old warning that citrus is poisonous to chickens is a myth — birds are not harmed by orange flesh, and it delivers vitamin C. That said, citrus is quite acidic and many flocks simply aren't interested, so it is a small, occasional treat at most rather than a staple.

How to serve it

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

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

In moderation — oranges are not toxic despite the folklore, but the acidity means small amounts only. The old warning that citrus is poisonous to chickens is a myth — birds are not harmed by orange flesh, and it delivers vitamin C.

How should I feed oranges to chickens?
Offer a few segments occasionally and see if your flock takes to them. Remove uneaten pieces before they spoil.
Can baby chicks eat oranges?
In small amounts, once chicks are around two weeks old. Because oranges is only a "sometimes" food for adults, keep it to an occasional taste for chicks, and offer chick grit so they can digest it.
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.
