NY 2, only calls I've tried using this early in North is a fawn bleat to get a doe attention. Or some light grunts, and light rattling. I've seen young bucks sparing in August, feeling their oats. I wouldn't do any estrous can bleats. Setup near food sources. I actually find this time yr. little easier, than the Nov. Rut. Not that bowhunting is easy, but deer are little more predictable, and bucks can still be in bachelor groups. This yr. the beechnuts, hickory nuts, and apples are plentiful. If you happen to find some acorns it could be hot, as there are very few acorns.
