Hard to believe that the deer would not be tearing up the corn at night. Are the dogs outside all night?
one horse, places like Michigan where you could bait forgot how to hunt. They simply build comfy blinds and put out the bait. To each their own and we've covered the baiting thing before.
I would get rid of everything except the corn feeder. Set it the farthest you can from the house. If there are deer in the area they will show up especially now.
