Wild hogs are very smart creatures. Any lactating sow in the sounder will nurse any pig in the sounder. A few sows are sometimes left behind to nurse the small pigs while the sounder searches for food and water.
One day i got between an unseen sow that was taking a mud bath in a pond and her pigs. Saw the pigs but not the sow. The pigs started squealing and here came big momma after me. Shot that sow. A few days later i saw another sow with several black pigs and the eight parti colored pigs belonging to the sow i killed.
Big wild hogs often develop a taste for fawns: i've caught them in the act of killing fawns.
i sometimes hunt on Ft. Sill, OK. West Range and Quanah Parker range were over-run with wild hogs. The fish and wildlife folks at Ft. Sill began trapping hogs with a purpose. Last year they shot about 450 wild hogs from helos. Hogs are now scarce on those ranges and in the surrounding areas.
IMO: The largest contributors to the out of control wild hog problem in OK and TX are the hog hunting "ranches" and those who run feeders. Here in OK selling wild hogs to the hunting "ranches" is big business. Some of those outfits buy hogs at the stock sales.
I've had good luck shooting wild hogs at stands overlooking this pig toy. It's 6" PVC that holds about 25 pounds of corn. There are four 1/2" holes in the pipe. The hogs toss it all over the place and are rewarded with a little corn. They sometimes hang around for hours until it's empty.
