There is nothing wrong with making a food plot to attract deer to your property. Realize though that it a lot of work and not cheap either. Deer will benefit which is a good thing. Also realize that during the rut bucks will travel outside their home ranges so the bucks you feed could get shot off your land but then again you could shoot one who moved in. Does don't tend to migrate unless they winter in a yard.
Also nothing wrong with baiting. You are a hunter who has made the personal decision to kill deer. Improving your odds of humanely killing one is what you should strive for. Baiting if done properly will not harm deer. Up until the close of archery they are still on the move and their metabolism hasn't transitioned into winter survival mode. If you were to bait in February that would be very different. If you can find it "the deer of North America" by Leonard Lee Rue will educate you on deer behaviour quicker then you can observe in the field. Deer hunting can be very addictive. I was for many years. My advice would be to not get wrapped up in the quest for scores. Kill as many as you legally can and you will learn something new almost every time. I have one nice trophy buck that I mounted and I smile every time I look at it. I'm just as happy to shoot a spike if it's what I see.
