A few days ago, I noticed a large black lump in front of one of my buff orpington pullet's comb. I didn't think of it as a big deal, until I found a scab on the back of her comb that was breaking away. She keeps her mouth open, and sometimes makes small weezing noises. My hen has been laying a lot less eggs than last week, and mosquito season just started. I think it might be aviary pox, does anyone know? Scab on comb Sorry about the quality of the photos.
