I've never heard of this. I put the used coffee and filter in our compost bin, but never knew it came in bags. I use sand in the coop and a kitty litter scoop daily is all it takes to make it stay clean. And of course we put the poop in the compost pile too. I can't imagine the amount of poop if they didn't go out all day. Next time I'm at the feed store I'll see if they have coffee grounds. Interesting!!!These are dried and bagged and sold in our box farm store.
