Our Theo had gotten into a fight with another rooster a while back. He lost horribly and I had to nurse a hurt wing and swollen shut eye from the ordeal. Those seem to be fine but now he has these bands of scabs around his neck. They only are from the side to side and not around the front. I looked him completely over and there are no other areas. I didn't see any lice or nits either. They hurt him because it is pulling on his skin and he has been stargazing. I assumed it was a vitamin deficiency since I had to force feed him and he probably didn't get enough food. He is on selenium, vitamin e and vitamin b. But this is confusing me. Any ideas on what it is?
