Oh my god. I was just at the feed store today and was horrified to find that their BR chicks were maiming each other. It was awful! I picked up a scalped chick that was bleeding and acting lethargic, and I gave it to a worker, who willingly cleaned the wound, treated it, and he placed the chick in a seperate pen to recover. That was a relief, but still, they kept on with angrily chasing each other and plucking feathers. He was unsure of what to do when I pointed out the severity of the situation, and went to the manager. What the heck was wrong, do you think? Stress? An overly-aggressive cockerel? Boredom? I don't know what would possibly cause such behavior!
