My Easter Egger Doreen is the only chicken in the flock with these weird whitish/yellowish spots on her comb. Some of the spots are flat, others are shaped like little tiny tubes. She has a pea comb with plenty of little crevices in them. For a while I ignored the spots, thinking they were just scabs or something, but they've been there for months and it doesn't seem to have affected her health. But after looking into it, it seems that she might have an issue. Here are some pictures, I apologize for the quality. PLEASE let me know what you think.
