I have a coop with a run that is chicken wired in...but the floor of the run (dirt) is always getting all muddy from the rain. I tried plastic over the chicken wire on the top but only succeeded in creating a giant water balloon in the plastic that has practically caved in the roof. I have heard sand is good but before I make a major investment, wanted to hear all the various ideas out there. We are so blessed with lots of rain in WA but I need it to dry up Help!
