Someone please tell me what is wrong with my hen! This just happened within the past 3-4 days.
I agree, fowl pox. It's a virus spread by mosquitoes that usually lasts 2-3 weeks. No treatment is required, but make sure that she eats and drinks well. If she has any pox near or around her eyes, Vetericyn eye gel or Terramycin eye ointment can help to prevent eye infections. If she has any yellow patches inside her beak, that can be wet pox which is more serious. Some people will apply some iodine to the pox scabs to help dry them out, but don't disturb the scabs, since it can spread the virus.
