I made some feeders specifically for coons but the same design will work for deer with corn.
- one piece of 4.5 ft long PVC pipe 6 inch diameter
- one pvc cap to fit the pipe
- one steel T rail fence post
- three pieces of 2 x 2 pressure treat 10 inches long
I used decking screws and you attach two of the pieces of pressure treated wood across the bottom of the pipe. Leave a two inch wide space between them in the middle of the pipe.
Pound the T rail into the gound so that there is four feet of it sticking above the ground
Place the pipe over the T rail with the wood spacers down
Fill the pipe with corn
Using the decking screws attach the third piece of wood to the top/outside of the pipe cap (makes it easier to get on and off)
Place the cap on your pipe
Your done. Gravity feeds the corn. I use cheap dog food for my coon feeders and found I had a lot of other critters eating at my expense so I fenced around them and cut small entrances so that dogs and coyotes couldn't get at the food. Still get possums, cats, foxes but they don't eat as much as the other critters. With corn I don't think you will have as much an issue and they should work well for deer. Pictures attached are with and without the fence. The bottom picture shows the two wood pieces and how much they dug it out when I didn't get it filled fast enough for their liking, lol
