First a brief description of my setup and then my question:
a- I' m on a 1000 acre farm. In different sections of the farm there is planted: Alfalfa (sp?), corn, wheat, hay, and soy. There are, tho in some places thin, wooded areas that connect all these places. I will be hunting in an area that has corn and alfalfa now, a deer pasture and an un-used pasture. By Oct 1st the corn will be harvested, the alfalfa will be too (I think), along with the rest of the things not in my area.

b- My question: What will the deer' s habbits be like when their main food supply (the alfalfa/corn/etc) is gone? Will they still frequent those areas looking for food? Will they scatter? Should I plan on looking for alternative food sources now for when they go to them?

Any help would be appreciated.

by the way, here' s one of my targets:
