I've noticed feeding corn makes them do it on my property. They know once the woods get quite and they shed their velvet that they can come feed at night. I've got 160 acres and can really only hunt 80 of so I try to stay off of it as much as possible but me and my brother can go hunt a weekend after not being there in two weeks and by the second day our deer sightings go way down. It doesn't take much to pressure a small tract of land.
