Wheat by far, is my only choice. Feeds the herd in the fall to early winter; then feeds them again in early Spring. Then continues to feed all types of wildlife when grain fills and dries down. Turkeys come in and can reach the shorter growing straw better. Common cover crop wheat is cheaper in price and does better on my soils than rye. Hands down my choice for deer, turkey, and other wildlife choices. I frost seed in late Winter with a good Mammoth red clover and create a perfect deer magnet.
