I don't know what it is like where you live but here in NH we have a set time we can use feed or bait, from Sept 1 to Dec 31. Reason being is the deer become too dependent on the feed and become too concentrated in one area. We also need to have written landowners permission along with a permit issued by the F&G dept. To me it makes perfect sense because when they do become dependant, they stop utilizing their own natural food source and they don't end up getting all the vitamins and minerals they require for a healthy diet which makes it tougher on them during the winter months. That's how it was explained to me by a CO I spoke with this year.

You should check with the F&G to find out what, if any, are the laws just to be on the safe side. I would think if the snow is really deep they would make exceptions to the rules if there are any.

Good luck
