Approximately a month ago, our younger chick was ataacked by an older hen. She was about 8 weeks old. Now, 4 weeks later, she has had her wound cleaned and changed every day. The tissue has gotten thicker but the tissue doesn't seem to be growing up the protruding bone. Does thins just take a long time? Or is there any advice on action we can take in this situation? I will post a photo from day 1, a week ago, and yesterday.
