I went down to my chicken coop today to give it a good clean out, but first a checked my birds...the first bird I checked was my roo and he had these little black dots on his comb and wattle! I checked my other birds, and only one other had them.... I am so confused. This is my first batch of chickens, so I got a few questions. 1. What is this? 2. Is this bad? 3. Can it spread if so? 4. Is there anything I can do to help/get rid of it? 5. Is it deadly? 6. Do I need to isolate them from the others? Heres the roo! I would get pics of hen but they are so small you would not be able to see them on my camera. Sorry if you can't see them good.
