No she isn't injured. She had a few feathers missing and did have some scratches but nothing major. She is in with the rest of the flock now and has been for the past 6 days. But they're still presumably picking on her enough that she flees up to the roost all day. I can't take the roost out because its part of the structure. Tonight I'll take her and a couple of the other super docile ones and put them in the chicken tractor. that way she's at least not isolated but is away from the main flock. There has never been anything like this ever in my flock. theres 16 of them, 2 are roosters, and they all just live happily together. Or at least they did until the hawk attack.
I went through the same exact thing with my buff ore, disregarding the hawk attack. She was introduced by herself into a new flock. I think because its a more docile breed they are more likely to get bullied. Anyway, she went up on the roost every single day, wouldn't come down and eat or drink until after the others had gone in the coop. I finally took the roost out and she was forced to be down on the ground. They pecked her a little bit, but in a couple of days she was one of them! It stinks you can't take the roost out. I like the idea of the chicken tractor.
