Trying to contain a hog population is just bad for everyone involved. Hogs will overrun your area even with an attempt to control the population with hunting. You will end up having to kill and burn or dispose of so many hogs that the initial investment will not be worth it any more and then what do you do with all the hogs you have left. Turn them free?? Kill them all (almost impossible)?? I agree with Hognut - eventually you will not even be able to give away the meat even if you kill and clean them.
