I use deep litter with pine shavings. Haven't changed them since April or so (although have added more), and still no smell. My run is just dirt, but they are free ranging now so it's not smelly either. I use Sweet PDZ and DE in the shavings and stir them up. And just in case you don't trust my nose, my husband agrees and he's only home on weekends so his nose still works properly.
October or so I'll do a full cleanout and start over with new shavings for the winter. Since the poo freezes in the winter, there's no smell there either.
