I have to say her wounds look far better and far healthier than I expected after I read your post. You are doing a good job. Are her wounds draining at all? If so, what color is the discharge? Her lack of interest in food is most worrisome. As others have mentioned, finding anything she will eat is a step in the right direction. Warm oatmeal? Warm scrambled eggs? Cheerios? Meal worms? Lettuce? I'd keep putting the Nutridrench in her water as well as using the heat pad. I understand the bit about bringing them in your house making it more stressful. I had the same problem with an ill chicken recently and opted to bring her in the house at night to sleep in the warmth and let her spend the day with the flock as she was much calmer then. I'm sorry I don't know what else to offer. There is no sure way of knowing if she has any internal injuries from the attack. There may be more going on that the visible wound on her neck. Keep up with the supportive care.
