Does anyone use egg cartons to feed their baby chicks? I was thinking about using the paper egg cartons in a brooder because I have so many chicks coming in this week and so many brooders set up I am thinking I don't have enough feeders. Thought if I used the egg carton if it got dirty I could throw it away and grab a new one? Is there any negative for chicks to eat out of it? Good idea or bad?
