Deer are social all year around its more a matter of how aggressive. Its always safe to throw out a series od doe bleats nad fawn blats it lets local deer know that other deerare in the area and going about thier business. Light grunting can also be worhtwhile as bucks will start to social grunt when they are heading in and out of fields to feed, at least this is what I have noticed in my 20 years of hunting, and I grew up hunting on the northern border of NY 5 miles off hte canadien border.
