i seen a guy use a drinking straw once as a wing bone type call,sounded better than any suction call i've ever heard and i've heard lots of calls(mostly all in my vest)
yup they say hen wing bones sound like a hen,jakes like jakes and tom like toms.
hopefully i'll get drawn for fall season in our lottery,then we can legally shoot hens. then i'll make a couple hen wingbone calls for my self.
peace,
tim
