Hi, I have a flock of 7 hens and 1 rooster who have always got along well. They have a large coop (we built it for 18 chickens), 3 nests, and a large fenced in yard. I normally put out one 3 gallon waterer and two feed bowls. I recently separated out one of my hens (white cochin, one of the bottom of the pecking order) because she is broody. My EE rooster has always mated with all my hens except one, my white EE. She is one of the bottom on the pecking order, she is fast. He would chase her around the yard but never seemed to be able to catch her. Recently I noticed her hiding from him a lot. She spent a lot of time on the nest or on the perch. Then one day I saw him catch up to her and pull out feather from her back. Then I saw him catch her and she finally submitted, he mounted her but instead of mating with her he just pecked her head and eventually let her go. I also noticed my partridge rock hen (also on the bottom of the pecking order) go after her once. I decided to add a feeder and waterer in the coop. The next morning I noticed that she had some red scabs on her head so I decided to set things up to separate her out. While I was doing that I heard squawking and my daughter saw the rooster and my partridge rock going after her. She ended up with a big gash on the side of her face, not sure which one did it. I have her separated now to heal up. What are your thoughts? Peck order fighting? Problem rooster? Other issues?
