I have play sand in my coop. In a year I changed it out. I added sweet pdz and diamathious earth. I turn the dirt periodically and rake debri up too. Odor stays at a minimum. The upper level where they roost I have a poop caddy. Hubby built it like a tool box caddy. The "handle" is the roost. Droppings go into the caddy. Also sand pdz and diamathious earth. Works wonders for my small flock. I put the old dirt in the back portion of my property. It's gone now. Rain has basically caused it to blend into the landscape. Used play sand from Home Depot
I think I read that sweet PDZ doesn't work if it gets wet, as in the run area. I'd love to put a bag or two in my run and mix it with the concrete sand that I have in there.
Does anyone know if this is true?
