Two of my hens have been sharing a lay box because both are broody and I've only allowed them to hatch one box. A baby hatched yesterday and the Brahama she was under at that time didn't seem particularly motherly to her, but I decided to leave the chick until this morning and see what happened. The chick was under both hens in the box this morning. I removed the Polish which apparently made her very angry because she then plucked the baby from the lay box & aggressively tried to murder it in front of me. I kicked & threw her off the baby, but she managed to leave a pretty severe injury where one of the legs attaches to the body. Its an open wound, looks like I can see a tendon. The baby is now inside and is silently chirping. Is there anything I can do for this baby or do I just wait & see?
