I mix about 2 cups in with my chickens treats about 3 times a week. I have 14 hens and a roo, never had any adverse reactions, and all of them LOVE it! I also give about 1/2 cup to each of my dogs a couple of times a week. They LOVE it as well, (in fact, they beg for it as soon as I start to strain off a batch!) and no ill effects with them, either.
