The deer here prefer oats over any other winter crop. Used to plant the expensive buck forage oats in our fall game plots; paid about $35 per 50 pound bag. Then i found out that plain old horse feed oats at $11 per 50 pound bag are just as hardy and the deer like them just as well.
Chilocco oats cost about $16 per 50 pound bag and are very cold tolerant.
