Got into some family groups

That trappers theory is ridiculous to anyone that thinks logically. Hogs unmolested in a decent habitat will reproduce until that habitat struggles to support them. At that point (if not before due to natural roaming) they don't practice population control, nor all die off. They venture out looking for another sustainable area. As population grows it spreads out, just look at humans. Look at the bear in Ok and Ark, there was a time there were virtually no bears there, Arkansas reintroduced them many years ago and they did well, began to spread out all over the state and into adjoining states. It doesn't take hogs as long due to their reproduction rate, bear do not raise cubs more than every other year, normally less than 3 are born . Usually do not breed before 3 years old or older. Hogs breed much younger (6-8 mos) have more pigs, and in a good year, may well have 2 litters. That old crap about them having 10-12 in a litter 3 times a year is not truly viable in hog farms much less in the wild, but still a higher reproduction rate than most wild animals, and have few natural predators.
