So I have killed some of my best birds late season as those hens go to nest and that tom loses his harem. I use a (I am going by DSD's I have) Feeding hen as she is portraying a hen off the nest to feed and such and then my White Headed DSD Strutter, the white head is a dominant bird but in breeding mode, a red head is fight mode. Dominance has long been established by this time. So the bird your working is a alpha by what I read. Having another alpha come in on those last few hens to breed, as these late seasons toms venture more to find those available hens. Now if all you have is the jake I would still set him with that feeding hen, give the decoys some room in between so as it looks like the jake is following a hen around. Remember your jake/tom is set at your point of kill, and have a clear path of that hen decoy.
I'll post it up but my bird "Hook" was a late season hunt and all you could see was fan and head, I put my hen on a "high" stake so her backline was above the hay, was getting tall!
