A friend that raises and shows chickens brought me over a bottle of this stuff when I told her my old rooster has a rash that won't go away. We rubbed some on his rashy area, legs and his comb. He seemed to really like it. I also put a few drops in their water. I can't say it cured his rash as it's still here-but improving (and I'm using another product on the rash as well), but he just seems to be doing generally better. I had a lot of the product on my hands, so I wiped it on hen who had lost a ton of feathers (due to bugs I think). I just rubbed it on her back and sides. The NEXT DAY her feathers started growing back. It could be a coincidence....but I love this stuff!
