My rooster, who seems very alive and well in all other ways, has what looks like white and black specks on his comb. Is this mites? I have attached a photo (sorry - it's black and white since something happened to the camera and I don't know how to get the colours back!!) Hope this is helpful. Also, it appears that there are feathers missing on his front neck/chin. We have had very cold temperatures for the last week or so. Any guesses at what it might be, if it's curable and if so, how? Thanks!
