I dont believe that coons are running your deer off at all, I have tons of pics with deer and coons eating together.Up until 2 weeks ago i was getting lots of deerpics in my food plots then here comes hurricaneIKE, he decided to blow bunches of acorns outof the trees,andguess what deer like them better than oats and corn. So check the ground in your hunting area and see if you have acorns on the ground.
