I just cannot figure out what is going on with our rooster, Jr. I have sprayed him for mites, and lice, with no improvement. I have also given him a 7 day course of IM Pencillin G. No changes. Has anybody ever seen this before? He is in a very large area (1/2 acre) with about fifty hens, and 2 other roosters. None of the other hens, or roosters, have this problem. He is the dominant rooster. Please let me know if you think you can help!!!
