The problem is not so much the inside of the hen house, which should stay dry, but the floor of your run, which will definitely get wet during heavy rains. My wife wanted to try the deep litter method for the our coop run and I noticed that even with light rain, run-off would hit the block at the base and splash in the coop. If there was any wind, all of the base litter would get wet save for a small area under the hen house. Since it was raining almost daily here for a while, the wet litter was getting messy and smelly, so I fitted some coop curtains using semi-clear 6x10' tarps. You can get on them on ebay for about $15. I rigged it so I can use a half skirt for normal rains and a full curtain for big rainstorms and snow. Working good so far, it rained last night and today the litter is dry as a bone.
