I noticed on my roosters bottom down low is a bare red spot. Some quills can be seen at the edges as if they have been pulled out. It doesn't seem to bother him, at least he doesn't act like it does. I applied Blue Lotion to the area. Do any of you know what it could be from and what else to do? I thought maybe the hens did it since sometimes I;ve seem the chase him off if he tries to mate a certain one. Any opinion please.
