Ok updat: coops 1 and 3 had 3-4 inches sand. Coop 1 I put a layer of straw/pine shavings on top of sand then a thin layer of limbs, clippings, leaves. I fluff it up a bit in the am and leave it in piles and Mr Ringo’s crew scatter it back in place. Coop 3 has 3-4 in layer sand only the tomorrow will have a straw/pine shaving mix put on top then whatever clippings and such we can gather. Coop 2 is still ground and that will get rest of the sand until we get more yardwork leavings to put in. We do not have access to lots of leavings so every mowing day is gathering day. It will take a while to build it up to dlm but I think with the sand, straw and shavings layers underneath that should be ok.
