I bought it because it suggested whitewashing your walls and roosts with it. Haven't done it yet (too hot outside) but I'd like to.... Especially in the duck coop on their beddingI've been using it for a few months. I sprinke it into the PDZ droppings pan, and on the sand, coop floor - then lightly scratch it in. I use an old, plastic parmasan jar with sprinkle lid for distribution
