Boy this must be going around! My Joon bug has it as well. Here is some information I found on it. I am giving vitamin water and ACV, but not antibiotics until a secondary infection happens (if it does). Antibiotics can mask the symptoms, but may not help get rid of the virus.
What I have been doing with my girl is putting ACV and vitamin mix in waterers, giving yougurt as treats, and cleaning the scabs on her comb with iodine. I have not seperated her from the flock, and am treating everybody in the flock with the above. I have read that when one bird shows leisons chances are the entire flock has the virus in their systems (whether symptoms are shown or not) so might as well treat the entire flock with the immune boosting probiotics. At least that is how I am doing it.
Fowl pox is very similar to chicken pox in people it seems, once they get over it the virus should not return. Right now my girl only has the dry version, I have read a few places that the wet version has about 10-15 percent survival rate, but the dry has 85-90 percent survival rate.
Basically it seems darwins therory strikes again. If the chicken's immune system is strong enough to fight it off, let them. You can aid with ACV, and others (look up probiotics), and if you feel better you can isolate the symptom showing bird. But do not be surprised if the flock has the virus as well unless isolation is very very well managed.
just IMO and personal experience. That is how I am treating my girl.
