I cannot see it too clearly, it's looking more pox like, usually when they get pox it is also on the face and sometimes the eyes swell and crust shut, I had it on my turkeys this year, I have never had it on my chickens though, it's just large crusty circles about the size of a pencil eraser that's called dry pox, if it's in the mouth and throat it's wet pox, that one is worse because they have trouble eating and drinking.[/quote
