I have 4 hens and 2 jakes. I also use "the love triangle", by setting up just 3, or all 6 decoys. I set them up with the hens closest to the blind and try to make it look like the jakes are harassing them. The hens are 10 yards out with the jakes at 13. This does seem like the decoys are right outside your window, but this gets the toms much closer before they stop. When they do, they are almost always in bow range. Have you tried this? I've never tried it any other way, just curious.
Thanks
