Almost two weeks ago I noticed a black spot on one of my wyandottes wattle. Spots are now on her comb and several other chickens either have black or white spots on their combs/wattles. My only guess is fowl pox. None are lethargic or lacking appetite. All are acting just fine sans the obvious spots on their combs/wattles. This is my first winter with chickens period let alone with a case of fowl pox. Anything I need to do in order to prevent it from getting worse? I've put vitamin/electrolytes in their water. Don't know if it'd help but figured it couldn't hurt. I've read conflicting things on treatments. Heard you can give some kind of injection underneath their wings or just let it run its course.
