Potatoes are a bit of a mixed bag for chickens. Cooked plain potato is a perfectly good scrap that hens enjoy, but the raw, green and sprouting parts of the potato plant contain a natural toxin. It pays to know which is which before you tip the peelings out, so let us walk through the safe way to share them.
Can chickens eat potatoes?
Yes, plain cooked potato is fine for chickens in moderation. Boiled or mashed potato with nothing added makes a soft, filling treat that most hens tuck into happily, especially on a cold day when something warm is welcome. The two words that matter are cooked and plain, which means no butter, no salt, no gravy and no fried chips.
Where potatoes go wrong is in their raw and green forms, and that is worth taking seriously, because it is one of the genuine hazards among common vegetables. Kept to plain cooked flesh, though, potato sits perfectly happily among other scraps on a chicken's varied diet. You will find plenty more everyday foods covered across our backyard chicken guides.
Why raw and green potato is dangerous
Potatoes are part of the nightshade family, and they contain a natural compound called solanine. Solanine is concentrated in the green parts of the plant, in green patches on the tuber itself, in the sprouts or eyes, and in raw potato generally. It is the plant's own chemical defence against being eaten, and it is toxic to chickens as well as to us in large enough amounts.
Cooking breaks down much of the solanine in the flesh, which is exactly why plain cooked potato is safe while raw potato is not. The catch is that no amount of cooking makes a green or sprouting potato safe, so those should always be thrown away rather than shared. If a peeling has a green tinge, it goes in the bin, not the run. When in doubt, the old rule holds: if it is green, do not feed it.
What about chips, crisps and roast potatoes?
It is tempting to hand over the odd leftover chip, but the fried and salted forms of potato are best avoided. Chips, crisps and roast potatoes are cooked in a lot of oil and, more to the point, they are heavily salted, and chickens do not cope well with much salt. A stray chip will not spell disaster, but these should not become a regular offering.
Stick instead to plain boiled or mashed potato with nothing added, which gives your flock the treat without the salt and grease. If you have mash left over from dinner, only share it if it was made without butter, milk or seasoning.
How to feed potato safely
Keeping potato safe for your flock is straightforward once the rules are clear. Plain, fully cooked flesh is the whole story; anything green, raw or fried is not.
- Feed only cooked potato, boiled or mashed, with no salt, butter or oil.
- Never feed raw potato, green potato or green peelings.
- Throw away any sprouts, eyes or green patches rather than feeding them.
- Provide grit so hens can grind their food, and remove leftovers before they spoil.
