I don't have a problem with it getting compacted. The chickens dig it all up and I do rake it once in awhile (mostly just to fill the holes they like to dig!), throw on some Sweet PDZ etc. Mine is 4-6" deep, I don't know what's going on "down below", but the top 3-4" is all nice and fluffy, it drains well and doesn't smell. It does freeze in the winter, but I like that because it makes it easy to sweep off the top layer of snow. The section in the foreground is sand, the stuff in the back, left corner is pine straw.
