We have the Playhouse coop for 3 chickens and the run is 4x8, the fooprint on the coop is maybe 2x4 feet.  I've been using about 3/4 of  cup total of DE every week when I replace the top layer of dirt in the run and on the pine shavings as well (which get tossed out every week.)
How much is too much?
