We have a raised coupe - currently there is rigid wire on top of the 2x4's. Then we secured cardboard (don't laugh!!!) to the underside of the 2x4's for the winter Of course it is all now a falling apart mess What if we created (using press board) 4 or 6 trap doors on the underside with hinges and latches - removed the wire mesh and filled the space (probably 6 to 8 inches deep) with shavings. then when we need to clean it we just pull up the wheel barrow open the hatch and DONE!!! (this will be added to our compost pile!!) AND can we use a mix of shredded newspaper??
