RE: what do you recommend to use to "fence in" my feeders?
The goat fence works good and so does the barbed wire. Just drive those t post in real good and know that this fence will not keep hogs out. You do need to drive 2 t post cross wise on each leg, just as deep as you can then bolt a chain to the leg of your feeder and wrap said chain around the post. This may keep the hogs from tiping it over.
Good luck
