I have been reading a lot on backyardchickens, but this is my first time posting on here. I have many chickens of different breeds and sizes. Mostly bantams in my front yard and standards in the back yard. I have 8 bantam chickens and one standard size chicken (they are all in the front yard) who have started showing signs of some kind of illness. It started out as a few bumps on the rooster's combs and now it's all over their faces and one has it real bad inside his mouth. It has gone from being bumps to crusting up with yellow scab like stuff. I have been cleaning off the yellow scabs and applying neosporin to it, but it doesn't seem much better. The bird's average ages are about a year, 4 roosters and 4 hens (banties) & 1 standard size hen have this illness. I have been reading a lot trying to figure out what it is, but I haven't found anything like it yet. My friend took a couple pics with her phone so I could post them on here: Anyone have any ideas what it might be? I look forward to your responses.
