Ok, I got some at my feed store and it is like flour?? Can I use?Sweet PDZ is a horse stall refresher that, in gravel form, resembles cat litter but it smells better. It's 100% safe for use with chickens (I use it!). I have a poop shelf under my roosts in the coop and it's filled with Sweet PDZ. I scoop it every few days with a cat litter scoop and it keeps allllll that crazy night poop out of the coop and off the floor. It's a very clean way of doing things and I have yet to replace or add to my shavings in the coop in 21 weeks of them living there. PM me if you want more info or have questions.
