Fowl pox is a virus that lasts around 3-5 weeks. There is nothing that treats it, except maybe to apply some iodine to spots (except around the eye) to dry the scabs. Don't mess with scabs much because it can spread the virus. Flies in the coop or mosquitoes can spread it to other flock members. Around or in the eye, I would recommend using Terramycin eye ointment or Vetericyn eye gel twice daily, but plain Triple Antibiotic will also work. Saline can be good if there is drainage to help remove it. Look inside the beak and throat if she sudden gets sicker or , won't eat, or has truble breathing, because wet fowl pox can form lesions in the throat and airway. Give her some extra protein from eggs, tuna, or a little dry cat food so she doesn't lose weight. Vaccines are available to those that haven't been exposed, but she will be immune to that strain once she heals.
