I found my chicken attacked yesterday evening when I went to lock them up. I have no idea what may have attacked her. All other chickens are fine. Her wounds are extensive. One side of her neck is missing down to the bone. I left her with food and water overnight and have tried dried mealworms, strawberries, and even cat food but she doesn't seem to want to eat. She is having bowel movements and I've seen her drink a little water. I'm having a tough time believing she can regrow all of that skin, but is it possible? Should we put her out of her misery? I have cleaned the area with sterile saline, warm water with hibiclense, and I've used spray foam neosporin and the wound spray on it along with some betadine. I just don't know how effective it will be on such an open wound. Any advice is welcome. I don't want her to suffer, especially if she has no chance of recovery.
