I'm very new to the chicken thing. I have a pair of chicks (pic below). When scratching in the yard or when eating in the dog crate (temporary housing) they peck at each others' toes and at their own toes, even with food right before them. I haven't seen any drawn blood. I've done some searching and can't find anything on whether this is normal behavior. I assumed they were mistaking their toes for worms, but wanted to ask the experts. And can you tell what breed they are? I was so excited, I forgot what the Feed Store clerk told me.
