My Favorite Rooster recently got these sores on his comb that I don't recognize being new to chickens. I did some research and I am not sure what he has and how to cure it. I really need some advise Please. When I noticed the sore, I looked at pictures I took a couple days before I notice it. The first picture was taken on 10/9/2013 and the second picture was taken 11/16/2013. So is this favus a fungal infection or fowl pox caused by mosquitoes? Please Advise?
