I am having an issue with my now 5 month rooster attacking my other hen. And I mean attacking he isn't trying to mount her, he tries with the other one, but this hen wanted nothing to do with him. I have my two older girls who are a little over 2 years old now (I used to have 4 of the older girls but two have since passed). I 5 months ago got 4 more new baby chicks... One ended up being a roo. The girls and roo have been hanging around each other for a few months now. My alpha female when I introduced the new chickens to them, always bullied my roo. She has just been kind of a bully period, she would purposely go out of her way sometimes from across the yard walk to where the little girls were hanging out and pull at one of their feathers if she could.she has gotten better as the little girls got older. But my roo would always avoid her. Until a few days ago, when his hormones kicked in. He became a little more aggressive with my Rhode Island hen when wanting to mount her, she now just runs from him, but my other female who used to pick on him stepped up to him like she usually does, this time he didn't run away, their neck feathers flared and they full out started fighting. My hen immediately knew she was not going to win this anymore, and ran from him, he proceeded to chase and attack her so I had to step in and I grabbed him. After the day went on he calmed down. The next day, it happened again. He went after her and attacked her again. Ripped out feathers, cut her face. Now she is terrified of him. They both then started to make weird noises at each other when they were too close, or when he got too close because she now hides under the nest box, but it seems now when he sees her it seems all he wants to do is attack her. He isn't doing this to the other girls, just her. I since have kept them separate when I am not outside with them. He isn't aggressive with me at all right now either. Has anyone had this issue with their rooster and has anyone been successful with his behavior stopping with whatever they tried?
