Thanks for that. Yes my run is full covered and there is no water issues whatsoever. So is your major objection to the hemp the cost? Also don't many coop floors have wood bottoms? I have read the sand pulls the moisture out of the dlm material and interferes with the breakdown.
Wondering...
I have a large chicken run with sand. I want to use deep litter method in it and am realizing sand is not great under hemp for the deep litter method. What about laying plywood panels on top of the sand and the hemp on top of that. I would pull out the compost for the garden in the spring...
