Hi guys, We've got a covered run that started out filled with sand. Six months later the run is now, not surprisingly, filled with a lots of chicken poop that looks like sand. We've tried saturating the area with water to let the organic matter drain through but that didn't solve the problem. Any ideas you can offer regarding stink and fly reduction, short of completely replacing the 2000 lbs. of sand and poop, would be much appreciated. Thank you!
