The dirt work that we did to prepare the site for our coop consists mainly of limestone dust/dirt. The gravel roads out here are all limestone and we live near the quarry. When the ditches get full of limestone run off the county digs them out and we had several loads dropped off out here a few years back. It is like what you'd get at the quarry if you were wanting ag or garden lime, only there is good black dirt in it also. Right now we have a few weeds starting to grow in it, but its pretty bare. We will be starting construction in the upcoming days and I was wondering if the "dirt" that is there will be good for dust bathing, scratching, etc. I will be adding DE to it, but will I need anything other(sand, pete, etc.)? Should I seed it to get some greens in there?? If so with what? Grass, clover, wild flower, etc.?? Thanks guys!
