There is a time and a place for everything, but in most cases feeding deer is a bad idea. Deer easily become habituated to feed and will certainly lose some of their natural wariness of humans. Once they get accustomed to coming to your yard, corn won't be the only thing they'll eat. Gardens and landscaping are prime targets, and you'll be inviting property damage not only for yourself but also for your neighbors. Soon this animal that we view as a magnificent game species will become a hoofed rat in many people's eyes. Also, once deer become habituated, the potential for collisions with vehicles rises.
