A feeder is typically a very small concentrated area, deer get spooked off of it during daylight and they change their behavior to when there is less danger associated with the feeder. Same goes for foodplots Of course a 1/4 acre plot where the deer have been spooked off of it during the daylight hours are going to change behavior too because they will feel more pressure than being on a 10 acre foodplot with the same amount of pressure. So proximity associated with the danger and the time danger is encountered will make the deer change behavior for the local deer, it does not necessarily a deer may get bumped, chased or accidentally come to it at other times.
Horsesheet. Go to most any home on Pike Road, they've got corn feeders in the back yard. Most folks I know down there come and go at all hours of the day and night, and see deer at all hours of the day and night. One of the biggest bucks I saw killed last year was shot off a guys back porch as he was heading to work.
