Quick Take
No, chickens should never eat chocolate; it's toxic, and even small amounts can be fatal.
There's no safe amount. The theobromine and caffeine in chocolate build up in a chicken and hit the heart, so keep all chocolate, cocoa and chocolate leftovers well away from the flock.

This one is short and firm: chocolate is toxic to chickens, and it's worth knowing why, because plenty of holiday sweets and baking scraps contain it.
Can chickens eat chocolate? The short answer
No, chickens should never eat chocolate; it's toxic, and even small amounts can be fatal.
What to avoid: all chocolate. It contains theobromine and caffeine, methylxanthines that birds metabolize very slowly, so the compounds build to dangerous levels. Darker chocolate has more theobromine and is the most toxic, and the sugar and fat are harmful too.
Is chocolate good for chickens?
There's no nutritional case for feeding chocolate to chickens; any minor nutrients are far outweighed by the toxic methylxanthines. It's better thought of as a poison than a treat.
How to feed chocolate to your flock
Don't serve chocolate in any form, including candy, baked goods, cocoa, or chocolate-containing leftovers. Keep it out of reach and off any compost the birds can access.
None. No amount is considered safe; as little as about an ounce and a half of chocolate can poison a bird, and dark chocolate is dangerous in even smaller amounts.
What to watch out for
Theobromine and caffeine can cause a racing or erratic heartbeat, tremors, seizures and cardiac arrest, and poisoning can kill within roughly a day. If a bird ingests chocolate, contact a poultry-savvy vet promptly.
Never give chocolate to chicks. Their small body size makes even a tiny amount more likely to be lethal.
The one thing not in doubt here's the danger, so we won't invent a safe amount; if a bird does get into chocolate, that's a vet call, not a wait-and-see.

Chocolate: common questions
Why is chocolate toxic to chickens?
Chocolate contains theobromine and caffeine, methylxanthines that chickens clear from their system very slowly. They accumulate and disrupt the heart, causing arrhythmia, seizures and cardiac arrest.
What happens if a chicken eats a little chocolate?
Even small amounts can be dangerous. Watch for diarrhea, tremors, a fast or irregular heartbeat and weakness, and contact a vet right away, because there's no safe dose.
