I put up a feeder on the creek a couple of weeks ago. The first night, the hogs knocked it over and pretty well wrecked it.
I recommend using 2 1/2 to 3 inch aluminum fence post for legs with t posts and barb wire. I have used the legs for two or three and havent had any of them break like I did with the smaller ones. This year we put U- bolts on the legs and fastened them to the t posts. I dont know if it will help but we will see.
