I have a 6 month old rooster that I have noticed in the last week a red patch and feather loss around his butt. I do not see any mites or viable bugs on the skin. Also, not sure if this is a rooster thing but the side of his legs are slightly red. Can somebody please tell me if this is normal for a rooster and if it’s not is there any suggestions on what to do. I have been giving my chickens, a small amount of tomatoes and squash lately as a treat, they consume regular chicken layer, pellet diet.
