! Y use lime?There is MUCH difference between de and lime. Lime is a caustic chemical. Diatomaceous Earth is the remains of the skeletons of microscopic diatoms, and are silica, like sand, and will dehydrate any insects that it gets on, hence death to mites and others. Dust your chickens with lime, and they can get chemical burns, but won't get burnt by DE. If it is a place where they take dust baths, use DE. I don't think I would use lime anywhere the chickens would make contact, although it will neutralize the scent of poo.
