Is it normal for the skin area around the vent to be red on a rooster that is "with" hens? It isn't just red in a circle around the vent, it is the whole bottom from tail to legs. I have two roosters each with their own flock and noticed (while they were pecking scratch on the ground) that both of them have really really red bottoms. One is a white mutt roo and the other is a barred rock. Both are about a year old. I have two RIR roos in a sepreate area w/o hens and they do not have this condition.
