I feed alfalfa hay as our primary feed. I have had excellent results but others have been mixed. I live in an arid region. Alfalfa may not be the best if you are in an area that has lot's of natural green browse. Oats sat on the ground and clogged the spinners on my feeders. Alfalfa doesn't draw coons. I also add a protein block and a mineral block at each feeder. Experiment, corn always works.

Build your stand high as you can and have multiple pathways to mind the wind. Ivory soap works fine. You don't have to be Rambo with a feeder and a blind.
