If the weather is cold in your neck of the corn field, I would suggest a nice warm 1/2" plywood blind. Make it 3 feet deep by 8 feet wide and 66" high in the back; 42" high in the front. Give it a 12 inch deep roof and a spring loaded trap door on the front, hinged on the bottom all the way across the front. Put in a 12 inch deep seat and a 5 inch shelf on the front. Cut screened windows on all sides and paint them thick so approaching ducks can't see in. Put plywood sliders inside each door to block the wind when necessary. Paint the outside camo/cornfield color and stuff cornstalks in clothesline that is stapled around the outside. This should keep you very comfortable, toasty warm, yet give you great shooting flexibility. Although it is somewhat portable, it is really too heavy to move often during the season. Therefore, I would suggest setting it up on the south side of your pond facing north. Place your decoys in a pipe shape with the duck landing area about 25 yards in front of your blind. A small propane heater will keep it warm enough to hunt in shirt sleeves if you prefer. I added a fold up table top in mine so we could play cards between flocks. You don't need water in a corn field to attract ducks but you will find that a couple of Lucky Ducks (with the flapping wings) make all the difference in the world. Good luck... it sounds like a great setup.
