Separate her, clean the wounds with weak Betadine, and put Neosporin on the dried off skin. Get some BluKote spray for when you put her back in after she heals a bit. This chick has major injuries to her throat, and it may cause respiratory distress or difficulty breathing. I would feed her some vitamin/electrolyte water for a day or two, give her some eggs or moisten her feed to make it desirable. I'm not sure she will make it, but I sure hope so.
