I didn't watch the video, but...I call in and shoot 1-2 birds a season by calling to them on the roost. I've had more than that fly the other way, but they always had hens roosted with them as it turned out. I've had a little more luck calling them in once they have already flown down...even call in turkeys each year that have hens. I've called in the hens with the gobbler coming in behind them. I think it's a crap shoot each and every day, but I love it and have been blessed to kill a few each year.
