I have found that hanging the waterer and feeder at a height about even with the middle of their backs works great, very little bedding and no poop in the water or feed.  I started out with a game bird/quail waterer (smaller drinking area, small rim) on wooden blocks, then after 1 week switched over to a regular hanging waterer.  I put marbles in the drinking area to keep them from falling in and drowning.  Third batch is going strong and so far no losses and nice clean water.  Also, we add organic apple cider vinegar (1 tablespoon of per gallon of water) to their water from day one.  Several different sources report this to be very good for them.  Good luck
