I say yes as to mature bucks. Why take the risk. Ive converted my feeder to gravity style you can poor a buck pile off to the side where they don't have to be exposed. That said I don't really like to hunt over corn, its a pain, it attracts hogs, theres the added cost, and having to feed up all the time puts me and my truck in my hunting areas too much, not to mention the loss of the challenge. Bait on!
