I hunt in Athens county, no corn fields around here.
The cow didn't knock over that feeder but they have in the past and might have this week. I'll know in the morning when I go back down.
The nocturnal problem is not exclusive to feeders or bait piles, if they are nocturnal on the corn, they are nocturnal everywhere anyway, you just have a camera to show you they are nocturnal at the bait pile.
If they have enough corn on the ground that there is enough left that they know they can wait until after dark and still go and get some, they will wait until after dark. If they show up after dark and it is all gone they just MIGHT change the schedule a little

The best way to almost guarantee a buck going nocturnal on a bait pile is to have a pile large enough that he always has food available to him even if he waits until night to go to it. He has little incentive to expose himself for the daytime trip when he knows he can wait and eat all he wants after dark.. Weather, rut, hunting pressure, deer densities, etc, etc all play into each situation keeping me always guessing and not all deer read the same books.
If I could have a way to widely spread-out 5-8 pounds of corn an hour after daylight, in the same area, same time,everyday, without the need to walk in there to do it, I would choose that option every time over some big ugly plastic feeder thingy sitting in the woods for sure. I do NOT run any feeder time after the early AM feeder setting, and I don't dispense much each am. There is typically no corn left at night. They still come at night to check and look for the stray kernel or two, but they don't stay long.
Just my opinion on bait piles and feeders
