Jus give us some time, I almost ran one to Louisiana a couple weeks ago
All u need is a large boar and a fertal sow and in one year u will have plenty to shake a stick at lol. If I'm not mistaken they can have around three or four litters a year and a litter varies with the amount of tame pig in the farel hogs blood. Tame pigs have more per litter then a wild/feral hog.
