I have two woods that I hunt regularly. I live up here in NW Ohio so its flat with lots of farming. My honey hole is a birthing/bedding summer woods. And when rut kicks in its a hot spot, killed almost all of my deer there. But after gun season is over and the crops are gone along with a little snow and a hard freeze this woods shuts down, and I know its not because they get shot because most of the surrounding area is no hunting and I am the only one that has permision to hunt. Some of it I know is that their is no real close water supply. But the other woods is just the opposite. A few deer here and there, maybe two or three "resident" does but not much. But boy in late December and January I have seen heards of twenty deer in their. This woods has a nice big creek and lots of oaks. Maybe your deer are deed, or maybe you just have to find their winter home?
