I'm glad you liked it! Sweet PDZ is advertised for large animal stalls, like horses. If that helps you find it! It's not cheap, but not super expensive. I haven't purchased a new bag yet, and it's been in there for quite a while, whenever I got it together... I don't even know when I got my chickens in there! Hahaaha - Wait I wrote it down... Around the beginning of April! So, three months! I probably put half a bag in there on top of the sand. And then I added the rest a couple weeks ago. I really recommend it!
