Hey everyone! I have four roosters right now, two OEGBs and two RIR's. My biggests RIR's comb's tips have turned black, like they've been frost bitten, but it hasn't gone below 60 degrees here, even at night. My two little OEGBs have black spots on the inner part of the comb. They're not scabs, the actual comb is black. =[ What could be wrong with them? I'll post some pictures in the morning. Thanks everyone!
