They do need space, as the population of whitetail increases you will find them in new areas regularly. Years ago we would only find them in the bottoms and living right with us. Now they are on the top of the mountain, a 1500 foot elevation difference with no permanent people on top. The rut certainly puts bucks on the move but their non rut areas are even smaller than the does. Lots of conflict with whitetail, much more than mule deer.
