Elkhair - I' ve got some small plots of winter wheat that I let go to seed - the deer and song birds particularly favor the ripened wheat. When the ripened wheat is mostly consumed, I' ve either mow the field and let it lay fallow ' til the fall planting cycle, or disk the field and plant buckwheat as an interim cover crop. As noted in the above post, keep on top of any needed nitrogen or lime amendments by soil testing. As far as a fall forage crop, I' ve had deer walk through the winter wheat to get to winter oats (Buck forage oats), so if you have a choice and limited acreage, consider the oats.
