Gravel under the sand and on top of the wire will help with drainage.
My husband does field tile for farmers for a side living. The idea of putting down chicken wire, then larger gravel, then sand will work great for wet areas. The only problem we are fighting with our run is mud. The grass was knee high in the spring, then came the chickens. It's down to nubbs now with alot of mud. They don't seem to mind it though. Next spring we are going to build another run and move them from run to run to let grass grow up. Kind of like sheep pastureing. It will be interesting.
