I made a post earlier today about my rooster, Vivaldi, who was acting oddly. Tonight I decided to give him a check-over and see if all was well with him. What I saw scared me. I lifted the feathers on his butt, and right at the base, near the follicles, were these awful warty-looking pustule things. They were bright red and looked not so much like they were bulging out from under the skin but like they were a growth on it. There were so many I could barely see the skin underneath. I have to admit that I got so freaked out then that I out the poor boy back on the roost and hurried back to the house without taking a picture or anything. I've known for a while that the skin stretching down to his legs has looked red and inflamed, but I (and I feel terrible about this!) never really checked it out. Vivaldi and I have never had the best relationship, and without a drop in laying or something to signify that he was sick, I never quite got around to giving him a thorough examination. I kind of thought that maybe he was getting chafed from mating too much or something. All the skin in the area is red and painful looking. Does anybody have any idea what this is, how to treat it, whether it's genetic and whether he can spread it to the girls when he mates with them? I'm really worried now, both about him and about the rest of the flock. Thank you!
