All the turkeys in SW wisconsin came from Iowa, There is a big river they had to cross to populate our part of the state. They did some stocking in Iowa County but Grant County and Crawford county had no stockings, the birds flew over from Iowa where they were stocked. However, not as a rule but often times, the smallest of obstacles will keep a turkey away. I have had them cross 3 fences to come to me and I have them walk back and forth for an hour at 60 yards gobbling but not want to cross the fence. It's a mood thing.
