I am by no means an expert. But to my way of thinking, you will also have BB's from the surrounding areas come onto your property and if at all possible, set up housekeeping. The important thing to remember is that, as long as your property is attractive to deer ie plenty of food and cover, the deer and yes the bucks will be there also. Its not important for the bucks that are born on your property to not dispearse, its just that your tract of land must be attractive to deer in general. "If you build it, they will come."
