I've done some research and here is a list of food items that are toxic to chickens. I've been avoiding this for obvious health reasons. Raw green potato peels - toxic substance called Solanine. Anything real salty - Can cause salt poisoning is small bodies such as chickens. Citrus - Don't know why. Does anyone else know? Dried or uncooked beans - Raw, or dry beans, contain a poison called hemaglutin which is toxic to birds. Avacado Skin and Pit - skin and pit have low levels of toxicity. Raw eggs - Not toxic but you don't want your chickens to get introduced to the tastiness of eggs, which may be waiting to be collected for you. Poop out an eggs and get a treat. Candy, chocolate, sugar - Their teeth will rot... No, it's just bad for their system, and chocolate can be poisonous to most pets.
