You can get DE at your local TSC. That's where I got mine. Pretty cheap. You can mix it in thier sand. Should not be a problem. I was having issues with the sand in thier run stinking from thier poop abd pee- and with the rain here in Georgia. I bought sweet PDZ and put that in thier run and under the coop and it seemed to help dry out to poop
But I have one problem I cannot seem to solve and that's the FLIES!! Any one have luck on getting rid of flies??
Look at my thread on flies! It. Got so many great responses. Man those flys a making me batty
