@leadfeather,

First off, try as you might. You're not going to "get rid" of the hogs. Fact, pure and simple.
A friend of mine spent thousands of dollars and heaven only knows how much money surrounding his farm with hog wire.
He eliminated a huge portion of the problem, but a few still get through. Kill 'em, back track and patch their entry point. ...but even then, it's an ongoing battle. All he did was tilt the odds in his favor.

As for the coons and squirrels? Gimme a break!
You'd have better luck going swimming and not getting wet! I've had bluejays big as vultures spend an afternoon hauling corn away from my feeder. LOL!
It is what it is.
