Need to hang a pipe-style feeder w/corn that the pigs can't get to. How high should the mouth of the feeder be???

I was thinking about 3 feet , but I'm not sure if the deer can reach it and the hogs can't??

Now don't all run at once!!

i think feeders suck[8D]i HUNT for my deer&elk

I hang my feeders so that the mouth of it is hip high. Thats around 33-34". Deer had no problems
