Hello, I'm new to chicken farming and I have a problem I hope you can help with. We purchased 12 new chicks and a week after we had them the littlest one began bullying the others and injured one so bad that it ate the meat on the wing of one to the bone. I got the injured chick out and doctored it and pulled the bully also. A week later a different chick began to bully one and drew blood. After I kept the second bully separate for 2 weeks and tried to re introduce it but 2 hours later it drew blood again. How do I solve this problem?
