I have a small flock of Rhode Island Reds as well as a pair of Rouen ducks. They all grew up together and have been together since they were day old chicks. They are all about a year and a half now, four hens, rooster, drake and duck. One of my hens is being bullied. The other three hens peck at her sometimes, but it's the two males that hurt her the most. She cannot leave the coop, and half the time cannot even get down from the roosts in the coop to eat or drink, without my rooster and my drake taking turns at her -- repeatedly. I have seen the two of them gang-rape her both outside in their run and inside the coop when she tries to eat or drink. And they don't stop -- they will keep taking turns at her over and over and over until someone intervenes and chases them off her. She has run away twice because of the gang rapes from these two, but has come back both times. When I go out to see them, she always flies to me and sits on my shoulder shaking. She was the first of my hens to finish molting, but her back is now bare from being over-mated. She has a large scratch on her side below her wing. I'm really worried that my boys may hurt her badly enough to kill her. They do not treat any of the other hens like this, only her. I'm at a loss what to do aside of removing her entirely from the flock, except I have no other coop or run, or anywhere to keep her. Any advice is appreciated!
