I let a fellow farm my land for free with the stipulations that he not plow in the fall and he leaves som of his crops standing in each field. In years that he plants corn we put soy beans in the feeders and in the years he plants beans we fill the feeders with corn . This gives the deer a balance of carbs. and protein. They also have an abundance of browse on the farm. I am inclined to agree that the deer that died were park deer living on browse and over ate on corn. Cattle will do the same if you give them to much corn they will eat until they die .
