I recently had a eureka moment that I thought y'all would find interesting. Last year (2019), I found most of my sheds along the ditches in my 10 acre main field. This year (2020), I found 0 sheds in the same spot. However, I found a bunch of sheds in a 3 acre field 300 yards away. I thought that was odd until my eureka moment: the sheds are around the wheat/oat fields.
2019 - 5 acres of rye, 0 sheds
2019 - 5 acres of wheat/oats, 7 sheds
2020 - 11 acres of rye, 0 sheds
2020- 3.5 acres of wheat/oats, 8 sheds
I know this is only anecdotal, but it's pretty obvious to me - deer prefer wheat/oats to the rye. It's not exactly a fair trial though because the rye is much further along than the wheat/oats by the time bucks start dropping antlers. Up north where it gets really cold over the winter and rye's durability is necessary, rye makes more sense because it won't winter kill. But in more mild climates, it might make more sense to focus on the wheat and oats.
Note: I plant my wheat and oats mixed together in the drill. Next year I think I'll do wheat fields, oat fields, and rye fields separately to continue this experiment.
