Coop Fresh Premium Chicken bedding is a two for one product. Designed to reduce odors, absorb messes, and help kick start your compost, Coop Fresh is a combination of straw, hay, and natural zeolite. Zeolite neutralizes odors and is a safe source of grit for your chickens. The chickens love to root around looking for the hay to munch on too. So while it works on tough odors, your chickens can forage through the bedding, getting valuable grit and tasty hay in their diet.
