I caught it in my chickens early and I picked the dry scabs off threw the scabs In the garbage cause the scabs can carry the disease for a couple of months. And what I did after that was I made a homemade solution and put all over where they had it I mixed rubbing alcohol and 3 percent hydrogen peroxide about half and half and just take it and make sure you rub it all over of where they had it and it cleared up and went away but I caught it before it got to there respiratory system and once they have it they can't get it again. It's a slowly moving disease but it can kill your birds after a bit.
