Feeder Question
#2

It should be enough depending on how well the ground holds up, if you continue to have problems you can put a feed pen around your feeder to keep them from getting to it. Thats what I do, but I have my pen set up where it will still throw corn on the outside to attract the hogs....I do still like sticking the pigs too!!!!!!

I have had tripod feeders chained to trees and still had the hogs take running starts and knock the legs off of them. Found legs on the ground and a feeder upside down chained to a tree with the spinner ripped off. I have been fighting this battle for a long time. The only sure fire way I have found if to just put steel eyelets at the top and hang it. The t posts do work pretty well, but down here in Florida I have my feeders in some really muddy places and even they don't hold. The coons "can" get to hanging feders though so make sure to get a spinner with some sort of critter guard.
