There is no cure for Fowl Pox.Supportive therapy is suggested.Clean Feeders and Waterers daily as well as the coop.You can apply Terramicyn Ointment to the scabs daily. Vitamins would be suggested also.You can buy poultry vitamins at a feed store or you can get liquid vitamins at a pharmacy such as Poly-vi-sol-Without Calcium.Lots of good threads on Fowl Pox here on BYC.
