In our area I’ve had good luck with using 12” diameter heavy wall corrugated pvc pipe in ~ 4’ lengths.
Board on the bottom with the pipe v-notched 3 times and a lid on top. Mount it to a tree about 1.5’ off the ground attaching it to the tree using a 1/4” x 4” lag bolt with a fender washer and leaning a bit forward at the top to keep rain from running back into the feed. Tie the bottom securely to the tree such that it can’t tilt or wobble.
Add a plastic jar of peanut butter with the lid nailed/screwed to the tree and the bottom cut off the plastic jar. Put it about 4’ up and 90 degrees from the gravity feeder to get them started if it’s a new feeder.
Holds about 100#s of corn.
Edited to add:
If in a field, etc., I posthole dig and use a landscape timber to attach the feeder to but a bit lower.
