it is not a very good idea at all. the birds dont only get "call shy" from being spooked..they also get call shy from going to hen calls time after time to find no hen. in nature ready hens will find gobblers. thats why many hang up. we try to reverse nature and make the gobblers come to the hens. it works..when the gobbler is that fired up or that lonely. could be the ugly bird lol. in nature female species pick and choose who they want to mate with and a couple dominant birds do most of the breeding. calling before the season is a good way to ruin your chances once the season is here and theres no reason to do it. practice your calls at home and do your scouting with your legs, eyes and ears not your calls. theres a pretty big problem with preseason calling in PA. with so many hunters doing it, it definently has its effects.
