I have a 8 week old chick. I noticed that she will rub her beak on the side of the coop. Yesterday she seemed fine besides she didn't really want to eat when I was giving them treats last night but her crop was full so I wasn't to worried. This morning I went out there and noticed that the side of her beak had dried blood on it. I picked her up and saw that there are marks on both side of her beak from scratching it on the wood. I am new at this chicken thing and I am pretty sure this isn't normal. What could be wrong? and how do I fix this?
