Good post Nub...and when it comes to hay, unless it' s a fresh alphalpha or clover hay, they may bed in it, they may not eat it.....like Nub says, you might do the deer more harm than good. A deers metabolisism slows dramatically over the winter unless the winter is extremely harsh, they' ll be fine. If you do feel the need to feed, find a high protein source of food and if you start, don' t stop or you could kill your deer especially if they abondon thier natural courses and become reliable on you. If the food source isn' t a good one, they could starve on a full stomach.
