Wonder Dust is awesome! I used it on a leg wound for one of my horses years ago and it really worked great. There is another product that I absolutely love, it's made by Farnam and its called Trifecta 3 in 1. It's an antibotic cream with pain reliever built in AND it repels flies. I haven't had to use it on any of my chickens yet but I have used it in the barn on anything from goats to horses and it works great. Just an idea in case you can't find the Wonder Dust.
