I found PDZ at the feed store after reading & researching on the internet....I LOVE IT! Makes for easy cleaning, cleans up the solid floor in my coops & takes care of the smell. I scrape up the poop, sprinkle PDZ & DE, rub it like scrubbing the floor and done. It's all natural and makes cleaning so easy. Thank you BYC readers who have posted threads on it. This site is very helpful and everyone's input on subjects gives us different perspectives.
