Good thoughts here. For sure, a difficult set-up. Like Number 17 said, you may want to step outside the norm here. The last few years, I have adopted using the fighting purr call on tough situation gobblers. Tom's do not like when other males intrude on their flock. I have pulled Tom's away from Tom's and a Tom away from his hen using the fighting purr. It does not work every time, but I have had very good results here. You may be surprised how well this works for you. It definitely is worth trying, best of luck! If you stay persistent and patient, you will catch him on the right day and he will ride home with you!
