We have a flock of 1 rooster, 8 hens and 7 chicks. The other day I found one of the hens sitting in a corner in the hen house with bloody feathers. I picked her up and found that the entire back of her head had been pecked open. I cleaned her and kept her in a separate box. Her head scabbed over in a few days so I thought I would let her out and keep an eye on her to see what happened. The rooster made a bee line for her and started pecking her head. She laid flat on the ground yet the rooster continued to peck her so I rescued her. I have never seen him mate with this hen and since she has been kept separate I have not found a single egg from her and we are still getting the same daily amount of eggs which says she hasn't been laying. Could this be the reason for the pecking? If not is there anyway that i can stop the rooster from pecking her? Any advice appreciated. Thanks.
