If a calf can get to it a hog can!
I work 365 on trapping and shooting the beast, they are endless.
There is a market for the hogs.

I trap an average of 80 a year off my place and I am loosing the battle.
Hard to win if I walk out the front door and turn left or right is 60 miles of forest in both directions. The deer hunter is supplementing the diet with corn and protein, the sow is healthier and raising bigger litter.
There was 11 in this litter.
I actually think it was 12 as I caught this single the next day. I had shot the sow in the pasture the day before as she didn't want to leave that litter of pigs as well as my JRT was working her over.
There was 8 in this one.
If there is predation it's extremely low mortality rate.
