Thanks Wtnjunt, that is what we are thinking, the deer are moving in and out all the time, so we believe it too depends on the doe Population. we are seeing some big healthy does, but not as many as we would like to see, but again they move in and out all the time.
As for Dogdocs comments, if we tried to manage age harvesting, are neighbors do not and wont, they shoot anything that moves, so really its no feasible.
