Thread title should be "Don't Feed Corn Short Term".
If you introduce it when other food sources are available so they have a chance to develop the stomach flora to digest it and then keep feeding it, it's a great source of nutrition and energy for deer. Deer that have a steady and regular source of corn are some of the biggest and healthiest in the world. Think Kansas.
I've been putting out 50lbs every three to five days for a couple of years now. I have no skinny deer here.
