First time poster...big time desperate! I've got 8 bantams - 7 hens and 1 rooster. They're free-range birds, outside at 7:30am and back in at dusk. They've got good quality feed (& lots of it), a 4 by 8 coop and 3 nesting boxes (but no eggs yet). My problem is this: One hen is fairly timid. I didn't see it when they were chicks, but over the last couple of weeks, I noticed that she doesn't come out of the coop when I'm tossing bread scraps. It bothered me, so I started working on her - talking, tossing bread into the coop, ect. Today when I came out to give treats, she came out but promptly got jumped by the other hens - forcing her back into the coop. Tonight at dusk, I heard some awful racket coming from the coop and I look in to see her being ridden by another hen. Thinking I might have a bully, I watched for a while. In the space of 15 minutes, 3 other hens did the same thing - pecking at her back and riding her around the coop. Why are they ganging up on her? More importantly, how do I stop it? Thank you.
