I have three three week old chicks and I was letting them roost on the edge of their brooder. One of them was facing the wrong way () and pooped on the outside. I have a liner so it wasn't that big a deal for me but when I went back to clean it it was gone! Since then I noticed the dog sniffing around and he has gotten at least a few more pieces. Besides being really gross, is it bad for him to eat someone else's waste?
