Um, no, no, and no.Mold is not good for anything living - person, animal or bird. Never, ever give moldy food. They will end up with botulism
--Penicillin comes from a mold. It's an antibiotic that is good for some people & animals with infections.
--Blue cheese is blue because of a mold. That mold is safe to eat (for people and chickens.)
--Mold and botulism are two different things. Mold needs oxygen to grow, while botulism is only a problem if it grows without oxygen. So you are not likely to find them in the same food. (Some molds are a problem, and botulism is a problem, but you are more likely to find those problems apart than together.)
