my rooster has what appears to be dry pox on his comb based on the images i have seen, the dry looking black spots. He now has a few spots on his comb the largest about the size of a nickle. they are the color of wet pox (yellow/white). Is wet pox only in their mouth? Can they get wet pox on their comb? I can't get near him to take a picture because he hates me and attacks me when I get near him.
