RE: Rattle, grunt, or neither?
I've hunted in Wisconsin for 38 years. At this time of year the Bucks do not want to fight, so do not rattle. I would use a soft grunt to get his attention in addition with some doe bleats. A curiosity thing. I was near your area this weekend and did not see any rut activity. What I saw was a lot of feeding activity. I shot a buck with a gun that had already shed one antler, the other fell off when he hit the ground. Seems early to me. There may be a third streak of rut activity near the 1st of the year for some fawns, but that may be close to the end of your season. As far as buck/doe ratio, not good enough for competition or agressive calling.
