I just had this happen to one of my Rocks. She had a little scratch on her neck and the next day she was all bloody and the scratch was now a hole. The other girls would not stop pecking at it which caused blood and more pecking. I removed the hurt girl for about a week, long enough for her to heal properly without the others picking at her booboo. Once I put her back into the flock everyone was fine and she got right back into the swing of things like nothing happened.
