I started with a chicken tractor but it was actually a bit of trouble to move around. The chickens pooping on the grass smelled a little bit after only a day or so. Now I have a 10x10 kennel with wire on the top, and also a tarp. It stays fresh and dry and I don't feel bad if they have to spend the day in there. It was a lot easier to build than the tractor as well. My yard is pretty large, it might not work in a smaller yard.
