Hi there. My 2-3 year old wyandotte too has this on his rose comb. I have had staph on my self several times, and am familiar with what it looks like. I thought this might be the staph as well.
My rod had several yellow balls of something protruding from his comb, and when I poked one of them, it came off in my hand, so I worked at the others, and the same thing. The entire comb basically had these pock-marks that were filled with this solidified puss looking stuff. I scraped all of it out that I could, and set him aside in a dog carrier for the day/night. I will see what he looks like in the AM.....
How did your punk end up? Ever get it tested?
