I got a free chick that had been picked at by hens. She had a scab on her head. I left her and the other chicks out in the yard. This one went through the fence where my hens are. The one hen picked at her scab before I could get to her. She reopened the wound on her head. The is a piece of flesh, possible brain matter? I am not sure. I cleaned it put neosporin on it and bandage it. What else can I do? I feel awful! she had been out in the yard before and never was bothered by the other hens. How can U tell if it is her brain?
