Dogs LOVE chicken poop, in any way, shape or form; it's like dog candy to them. Mine have never been hurt by it. I had one dog who ate dog poop, and I finally broke him of that, but both of mine love chicken poo. (and deer poo, and cat poo...) I gave up worrying about it. When I told my vet what they did, she just smiled and said she'd have to check them for coccidiosis some day (she was joking).
