In the past week both of my bantam roosters have developed large orange swollen lesions on their face, comb and waddles. I have been googling chicken diseases online and cannot properly identify what is going on. Can someone please help so I can figure out how to treat them. I have 6 bantams, 4 hens (who do not appear to be infected) and two roosters (both have lesions) . They are in a coop with clean conditions, water and feed. They free range during the day. I also have 7 large chickens, 1 rooster, 6 hens in a different coop, and they also free range. None of them seem to be infected. There are two donkeys on the property as well. The picture is of Smokey and he is by far the worse off. Any advice is GREATLY appreciated. Very worried.
