Quantity
A chicken would need to consume and crush multiple apple seeds for a dangerous dose — a single seed is unlikely to be lethal. But cherry pits and stone fruit pits are larger and contain more amygdalin per pit. The safest approach is to remove all pits and seeds before offering fruit.
Notes
The most common exposure is from kitchen scraps: apple cores, cherry pits, and stone fruit scraps tossed to the flock. It's easy to forget that the seeds are in there. Apples are otherwise a great chicken treat — just core them first. Free-ranging chickens under cherry or stone fruit trees may also eat fallen pits.
Negative Signs
* Rapid, labored breathing
* Bright red comb that suddenly turns pale or blue
* Stumbling and loss of coordination
* Convulsions
* Sudden collapse
* Death can occur within minutes to hours depending on amount consumed
FAQ
Q: I've been throwing whole apple cores to my chickens for years. Have I been poisoning them?
A: The dose from a few apple seeds is quite small, and many chickens swallow them whole without cracking them. But their gizzards can crack seeds, and the risk is real over time. It's an easy fix: just cut the core out before throwing apples to your flock. No reason not to.
Alternatives
Apples (cored, seeds removed), berries, and melon are excellent fruit treats for chickens. The flesh is perfectly safe and nutritious — it's only the seeds and pits that are the problem. Core your apples and pit your stone fruit before tossing them to the flock.
Risks & Disclaimer
If you suspect cyanide poisoning from fruit seeds, this is an emergency — there is no home treatment for cyanide exposure. Contact a vet immediately. Cyanide acts fast, so speed matters.
