Dry Fowl Pox will generally resolve itself in few weeks. Keep watch on any scabs on/near the eyes - if there are any there, then apply some Vetericyn Eye Gel or Terramycin Eye Ointment for the eyes. As @chickengr
has suggested, apply Iodine to any scabs on the comb/wattles. This will help the scabs dry up. Don't pick off the scabs.
Make sure you are keeping your water stations wash and cleaned. Some people do add some Iodine to the water to "sanitize" it as well (in link below).
Antibiotics are usually not necessary for treating Dry Fowl Pox. If you suspect worms, you may want to take a fecal sample to your vet for confirmation, before treating.
