I have game cameras set up at my feeders. Deer do not come running to the feeder when the feeder goes off, I think that is what everyone thinks. There is days I don't even have deer at the feeders per game camera pictures. I actually have more luck and better timing of deer heading to the corn field I hunt. They move through the creek bottom around 6 pm- 6:30, they feed in the corn from 6:30 to dark. Talk about a set schedule.
My feeders have deer at them all random times of the day. And coons, birds, coyotes, bobcats etc........
