I have a California White hen that was attacked by a dog three weeks ago. Some of her tail feathers were ripped out but she was otherwise unhurt. The tail feathers have started to grow back but every few days I've noticed that they've been bleeding. I'm suspicious that the other hens might be pecking at her injury and causing it to bleed. Is there anything I can put over the tail to prevent more damage? I can't keep her in the house and its too cold outside for me to take her away from the other hens. I'm very worried about infection if this keeps happening.
