Oh yeah...farms acquire odors...and flies.
I overkill a bit, too...we move the tractor all around our yard, and when it gets within about 20 - 30 feet of the back porch, I want as few odors as I can manage. With our horses, it can get whiffy in the heat of summer, no matter how much you muck...trying my best not to add to the stink. I DO use shavings in the nest boxes (that helps deodorize a little, too).
