I know that chickens can't eat certain foods such as avocado and apple seeds, but I was wondering whether or not they can eat potato leaves, from the plant its self. I know they can't eat potato skins, and I haven't fed them those. Also, potato leaves are poisonous to humans, and I am worried that my chikens may eat the poatato leaves in my garden when I let them out into the yard. Will the leaves harm my chickens?
