More than a month ago I got a new silkie cross hen. She is bigger than a silkie but smaller than a standard size hen. Our rooster is the flock leader and attacks her whenever he sees her. I was wondering if maybe it's because she's so buch bigger than him (he's a bantam) and so he feels challenged...? She never challenges anyone and always runs away. I though that his attacking her was just a first time thing that he would get over after a few weeks, but he just keeps doing it. I really want to be able to integrate her so I don't have to keep her separate, and I want her to be happy. Any ideas? Thanks!
