“ This wouldn’t even have been a story in other states such as Texas..... ”

Agree. As a Texas deer hunter I’m on a lease with some other hunters. And, we have killed lots of feral hogs larger than that little piglet. The owner of the rancher encourages that we kill all we want. For those who may not be aware of pig fertility; get out your calculator; a sow can become pregnant and deliver 10 ~ 12 piglets three or four times per year. The females, approximately half will reach puberty in about six months to a year. So, do some factoring, using your own assumptions. But, whatever calculations are used you’ll wind up with a bunch of pigs. It’s difficult to kill them as fast as they’re reproducing.
Gestation is 113 days for pigs.
2.2 litters per year is the maximum.
