I hear this every year.."if you feed corn and deer aint use to it they can die". I know SO many guys who dump corn and I am not finding a bunch of dead deer. Also in Texas (no corn fields), they feed more corn then you could shake a stick at, they have extremely high deer numbers.
In the wild you have some apple trees (Arkansa Black I believe) that hold apples very late into the season. So your telling me that the deer, who are survivalist would die because of a late dropping apple tree if they ate to much?
I truly believe this topic is brought up every year, and the best facts I can find is the outdoor life article. Atlas in Ohio, I don't believe deer eating corn, apples, alfalfa or anything else people put out will hurt the deer in anyway.
Just had to share!
PS: I always check stomach contents- i find it too helps you learn about the deer, where they have been, etc. I also do this for turkeys.
