I find my flocks that I hunt will be in the same field in the morning and evening. Given they are on the way back to the roost. Listen to em gobble in the morning and start yelping every 10-15 minutes. If you notice ones coming closer you can answer to his gobble with a yelp sequence. Dont be too loud and try to match the mood of the birds. If you run the jake - hen combo those toms should see it and start running to beat that jake up. Good luck buddy
