There are plenty of places that allow you to bait deer as well as feeding deer. I've baited in the past and plan to put up a feeder this year after a few years off.
So why bait deer? It's far from unethical, in fact it's much the oposite. What you'll find is that more deer will be feed and fattened up to survive the long winter months when food is scarce and they hunker down to survive. Second, in the states before the steers go to market, they've been grazing in the pastures on grass. When was the last time you ate grass? Not very tasteful is it? So before they are taken to market, the farmers feed them corn to fatten them up and sweeten the meat. Do that to your deer and they will be very tastey on the plate. So when you get down to it, baiting amounts to harvesting your free ranged animals while giving back to the herd. It's good all the way around.
So how do you do it? Several ways from dumping corn out on the ground to tossong it out a scheduled times. I've only dumped 50# bags every few days. It will go quick. However, you'll be surprised that one deer doesn't gorge itself and pass out. They hang for about 10 mins and move on. They like a balance diet as well. I'll be going to timed feeder this year just to stretch the corn and to better pattern the deer. Good luck.
