Coop ‘N Compost Odor Neutralizer is a specially formulated product that can help prevent the buildup of harmful ammonia odors in your coop. Beginning with a clean coop, sprinkle the granules liberally over the floor, then add clean bedding on top. The granules work by absorbing excess moisture which keeps the bedding drier, and therefore, preventing odors. To freshen up the bedding in between cleaning, apply the Coop 'N Compost Odor Neutralizer granules over the surface of the bedding and stir lightly to break up the surface. Coop N' Compost Odor Neutralizer not only helps extend the life of your coop bedding, also improves the quality of your compost. Contains zeolite--a naturally occurring mineral group with a special crystalline structure.
