I've found it difficult to out-call real hen, even if I yelp, gobble, and my decoys are in plain sight. If they don't come in immediately after fly down, I've had some success by getting the boss hen riled up by returning her calls with some intensity. Since both gobblers and hens have a peck order, it is sometimes possible to get the boss hen to investigate the hen that is challenging her, dragging the gobbler in with her. If this doesn't work, I sometimes just sit tight since around 8-9 a.m. the hens will leave the gobbler to go nest and since I'm yelping/gobbling every 15-20 minutes as a reminder that I'm still there, hopefully the now lonely tom will come and investigate the new hen and intruder gobbler. Or...sometimes I set up in the field I assume they will be headed for after fly down. With occasional yelping/gobbling, I hope to give the message..."I'm already here. Where are you?" Be vigilant since gobblers often come in silently to size up the intruders.
