I've been using sweet PDZ mixed with some shavings on the poop board and sprinkle some occasionally in the bedding on the floor of the coop. It's awesome with no smell and the poop is a breeze to clean as it dries up well. When we clean the usual 2 minute daily coop maintenance cleaning and especially when we do our big 2x/year clean sweep/wash down in the coop, we take the shavings/poop and assorted whatever that is mixed into it (including the PDZ) gets spread under large trees as compost. Does the PDZ affect it? Anything in it that would harm the plants?
