Though there are many differing schools of thought on this one and many remain unconvinced about the wisdom of not giving this to the poultry, it is better not to. Anyway you will find that chickens themselves avoid eating this, then it makes no sense to add it to their feed bucket.

It is said that green potatoes have a toxic called solanine that is not good for poultry so avoid the green potato skins for the feed bucket. But you may include the normal potatoes or the ones that are cooked to the feed bucket if you wish to do so.
