Hello, I have never had such an aggressive chick before. The second I put my hand in the cage to clean, feed, water.. it pecks SOO hard and jumps against my arm and hand. It looks for a fight. I have grabbed him and held him upside down for a few seconds and put him back. He stays calm for a minute or two and then he's back to attacking me. He is in there with a few other very tame and friendly chicks. They are only 4 weeks old and he has drawn blood! He is going to go regardless, but I was wondering if he is just protecting the other chicks (by the way, he is the smallest one in there). Can this indicate that it may be a rooster? Thanks..
