I think that the answer is yes, but I wanted to ask the experts. I have seen these black, raised spots on my hen's comb in the past few weeks and have been observing them. The look of them reminds me of street tar that has been dripped onto their combs. They have changed and multiplied a bit but often appear shiny. Just this past week I noticed that my BO had some of them appear on her comb where there were none before. Here are some pics of my Welsummer with them. She was the first one I noticed them on. Also this past week I noticed that this girl had black streaks, even more like something dripping, appear on her wattles. In the above picture they are clear. It was taken maybe 2 weeks ago. All chickens have started laying again this week after almost a 4 month respite. I assumed that was due to their molt, winter, etc. Is this avian pox? ps- Also in the first pic there appears to be a 'crack' on her beak halfway in from the tip. Has anyone seen this before? Should I be concerned? She doesn't seem to have any problems with it (she's almost 2 years old).
