I have my coop downwind of my house. I also have it close enough so that I can go out in all kinds of weather to take care of the girls without too much difficulty, but far enough away so that I don't feel like I'm living in the barn. I use the deep litter method with wood shavings and haven't had too many issues with smell. The only time it smells is if the litter gets wet from rain, which is rare for me. Occasionally, I'll have a storm come in from a different direction and then the rain comes in through my pop-door and vent - when this happens, I have to do a total clean out of the wet shavings.
