Please tell me what you think of Roscoe's comb. At first I thought he'd been pooped on, but it has stayed for over a week now. The tips are more blackish than the photo shows, and then there's whitish stuff that looks like poop dribbled down. The blackish part looks kind of gooey. Could it be frostbite damage? We had a wet and very cold spell. None of the others have this.
