OK my 2 cents. You didnt say how much property you or your neighbor have but if the neighbor logged (chain saws, skidders and all the ruckus) the deer probably did move. They (hopefully) moved to your land!

Was it a clearcut or selective logging or thinning? Selective cutting or thinning can be a blessing. I bet they didnt go far. Find the babes (Does) and you find the horns. Good luck
