I've searched the forum for the answer to this and didn't find anything -- how much DE do you put down in your coop/run? I just recently found out about DE and I have been putting it in the coop and in the run (which is pure dirt) after I clean everything out every week for pest control. My question is how much are you supposed to put out? Do you need to reapply every day? Every week? I have just been sprinkling around a few shovelfuls - the run area is about 200 square feet or so. Thanks for your help!
