I went out this morning and my regular layers had viciously attacked one of their own. She is a leg horn, probably around three. The whole back of her head is bloody right down to the bone. It appears that they 'scalped' her. I put her in a separate cage, with food and water. For the first hour she just laid there, not moving too much. I just went back out again, expecting to find that she succumbed to her wounds, but surprisingly she is up, eating and drinking. So, she has a good fight to her, but what do I do about the injuries. It appears that from about the top of her head to her neck is bare. It seems to have stopped bleeding but is just raw hamburg. Any suggestions are appreciated.
