I just came home to see that there were feathers all around my coop. Somehow a hawk had gotten in and killed one of my 2 month old Gold Stars and scalped one of my 3 month old Wyandottes. It literally flew out at me when I came up to the coop. The other three escaped to safety but Rosemary is severely injured. The top of her head and the top of her neck scalped back to the "meat" and she must be in pain. She is still walking around and is jittery but I am new to chickens and have no way to know how to treat her. PLEASE HELP me help Rosemary!!
