Sorry if this has been asked way too many times in the past, but I'm a bad speller and my searches aren't turning up too many results. About DE in the coop and run. Do you have a specific amount you like to use or do you just scoop up a container full and sprinkle it around...are we talking just a little dusting or a layer? Say for instance I had a one-cup measuring cup...how far would that get me? I noticed there are big warnings on the side of the bag not to inhale the dust. I use deep(ish) pine shavings inside and out. The run is about 4x11 feet and the house is around 3 1/2x5. I refresh the shavings every so often and then compost/toss old ones on the garden.
