I have two hens that do not get along at all! Gwendolyn, a larger, more bossy hen has been attacking the smaller hen, Chick. Chick has marks on her face where Gwen has poked her, but the strangest thing is her behavior. Chick has been sitting on the roosts inside when the other chickens free-range. If I open the door to see where she is, she crouches really low and gives me a please-don't-hurt-me look. When she does come out, she crouches, and barely eats. If she does try to eat Gwen will bite at her and lift her neck feathers aggressivly. This has been going on for a few weeks. I'm not sure if this is the reason, but a few months ago Gwen went broody. Even though she had her own nesting box, Chick would sit on Gwen's head and shove her freshly laid eggs underneath Gwen to have her take care of them! These girls turned one in August. Help!
