Help I came home to find my chicken like this. The back is fully exposed and I can see some bone. I put vaseline on a paper towel and placed that across her back but is there any hope? There is no blood currently.
Wash the wound with Luke warm water, flush the wound with hydrogen peroxide, iodine or betadine, or if you have some blu kote on hand spray the wound with it and keep her confined away from the others Somewhere clean, warm and cozy.
