We have 10 hens and no roosters. My 3.5 year old son loves them and picks them all up. We have one barred rock hen "Dora" who is at the top of the pecking order. Problem is, she's very mean about it. She will run over and peck another hen in the head if she sees them eating something good. She was pecking us on the back of the legs out of the blue, but has stopped doing that since I grabbed her and held her on her back when she did it and drew blood on my leg! I just don't like how she treats the other hens. Is this normal, or is she just a mean hen? Should I get rid of her? I'm worried about my broody hatching chicks around her. I can imagine her pecking one on the head and killing it! Thanks!
