Welcome to BYC. I agree that it is fowl pox. Do not disturb the scabs or it can spread the pox virus. There is no treatment for the pox scabs, except that I would apply some Terramycin eye ointment or Vetericyn eye gel to the eye with the scab to help prevent eye infection. Make sure that she is eating and drinking well. More rarely, wet fowl pox can cause yellow patches inside the mouth, throat, and crop. Normally, dry fowl pox goes away in a few weeks, but it can slowly spread through the flock.
