Getting ready to move my four, 6+ week old chicks from the brooder to the coop with attached run. Just finishing up some last minute details. Now, I know everyone has opinions about what to put down on the ground. Right now it is dirt with a bit of grass under a covered run. I have some dry leaves from the fall. Would that be a good idea? Many people like sand, but won't I be wasting a lot of sand when I clean out the poop? Am also wondering about DE. If you use it, how much? I know it's used for mites and lice, but would it also kill the bugs that they want to eat? They have just been eating chick crumbles so far. When I move them out should I add chick grit to their food or put a dish out? Lots of questions, I know. Thanks for your help!
