Me and my son also have a May season in Wisconsin. His is the first week in May and mine is the second week in May.
Hope things start looking up by then. I have not seen a lot of strutting or many turkeys. I have even seen the hens seperate from the toms.
Maybe because of the cold weather? Not really sure but I hope it warms up before our season starts so they are out in the fields more.
Good luck during your season!!
