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.
