RE: 10 point
You may be causing the problem yourself with the feeder. Deer tend to feed in the dark as a rule but often have to extend their feeding time into the daytime hours because the food is scarce and more time is needed to fill their belly. With a well stocked feeder they can gorge themselves within a short time period and they don't have to expose themselves in the daylight.
Of course there are other factors too, like hunting pressure.
