Keep in mind that putting up a fence is to keep in what you have not to restock from somewhere else. A well managed preserve actually will have to give away deer once a year to other less managed preserves. This month at Temple Ranch in Freer Texas they giving away over 300 whitetail deer. You have to ask way in advance for them though. These deer will be typical Boone and Crocket 140-180 points. The idea of a well managed hunting preserve is to repopulate, not obliterate.

I was down there in 2011 to build a hunting lodge so I remembered this link.
These deer HAVE to be given away or they will be overpopulated. Like Jon stated, your county extension agent as well as your game wardens can help you do it the right way and give you people who give away deer to help you populate yours. Even if you had to drive all the way to Texas, and picked up 20 deer, it would be worth it if those deer valued at 15k each.
