Deer don't care
I can agree and disagree with that. Sure several deer come a running to the sound of a feeder going off to the point that there are electronics/calls that mimic the sound of a feeder going off, but I believe there are also plenty of deer that do the complete opposite under hunting pressure.
We use to get plenty of mature buck pictures at our feeders. We started hunting them and most of the time they will come through here and there but not usually regular and wont stay long. Put hand corn out with a camera on it and they come to it much better.
