I use HiFiber Gold from Lucerne the same company that sells Koop Clean. It is less expensive. I add some PDZ which absorbs the ammonia. I also use PDZ in my poop trays under the roosts, which i scoop daily. The HiFiber Gold lasts a year. In September each year I do a complete coop cleanout. I have builders sand in my runs that I clean once a week. My coops have no smell and the HiFiber Gold has eliminated bumblefoot among my birds. As far as I can tell Koop Clean is just HiFiber Gold with PDZ mixed in. The HiFiber Gold is a chopped hay horse forage that is heat dried to kill any mold. The chickens pick through it and eat the seed heads. It will last for a year and slowly breaks down so that when I shovel it out into my compost heap it composts well. The PDZ keeps the fly population in my coop down to almost 0. It also keeps my compost free of flies. Great product.
