Fowl pox is a virus. Here is a picture of favus, a fungus infection on this silkie's face. It is a white chalky powdery infection, and looks alittle like your picture. Favus is treated with antifungal creams such as miconazole and lotrimin. Of course, fowl pox in silkies looks a bit different than some of the common pictures.:The information is scattered among various posting folks. So ll I have to do is apply the iodine topically, around the face but not directly into eyes or nostril holes? I have Betadione, that is for topical use on horses. It is ruby brown in color, just like iodine. Unless someone knows otherwise, I'm going to try that. What causes the pox? Internal or external parasites? Apparently not a virus. Thans so much again.
