I use a Jake facing my blind at about 10 yards & 2 hens facing away about the same only to one side & a couple yards from the Jake. If he addresses the Jake he will face him & if he goes for the hen he comes from behind (supposed to anyway). either way, gives you a shot between you & the decoy & him facing AWAY from you.
This will be my 7th year (missed last year) but it IS a RUSH for sure. Good Luck.
I use a Ameristep Blind & just ordered another for spring. They don't pay any attention to them unless you make noise or they see movement.
