I have two 5 month old buff orpington roosters. Both seem very healthy, are eating well and have good weight. I purchased them along with three other buff orpingtons. They are from the same clutch. All are very healthy except for one thing I noticed within the past week on one of my roosters. He has what looks like a red rash going up and down both of his legs onto his feet. The other rooster does not have this. I read on one website that it could be a sign of excellent fertility. I do not let them free range. They are all kept enclosed (as we have too many hawks constantly flying overhead looking for a tasty chicken dinner). Their enclosure is all sand. The coop is cleaned regularly. Does anyone have a clue of what this is? P.S. He does not have mites or any bumps on his legs, only the red looking rash.
