CNC - Honestly can't figure out what you are trying to prove on some doe dispersal theory.... yea.... they move around and expand. Obviously. How they do this is not really an issue.

They walk across roads the same as they walk across a property line... they don't care. It's just part of their neighborhood. When the rut comes and movement in general is up across the board there will be more deer laying dead on the side of the road.... another obvious.

If you have low deer numbers and low doe numbers you will have near zero buck numbers. When you stop shooting them they come back some from surrounding areas like a cow.... they go to food sources. This is why your neighbor can plant a corn field and draw the deer from your property to theirs.

it's really simple. Think of deer like cows... they are just not in a pen and you can't doctor them. Other than they this is very similar to free-range cattle or sheep or any other animal.
