You boys will want to kill those hogs just as fast as you can. Some people think they shouldn't kill too many, because they want to be able to hunt them later. Well,you may know this, but one sow can have three litters a year with around 10 piglets per litter. Those piglets will be able to reproduce within a year. You do the math, it don't take long for Them to Get out of control. The more pigs there are in an area, the more hunting pressure they get, and soon enough the big lumbering pigs that you see wandering around fields go nocturnal, and become very hard to find and kill, but continue to reproduce.
