Sores on chickens

It looks to me like it is dry fowl pox, a virus carried by mosquitoes. It usually last 2-3 weeks, and can cause a lack of appetite, but usually isn't serious, unless there are yellow lesions inside the beak and throat, or if the eyes get infected with a secondary infection. I would probably use some Terramycin eye ointment in the eye twice a day. Here is some info:

Thank you. That is exactly what they have. I guess I will have to let it run its course
