I have shot a number of birds coming in to a single hen decoy. I have also seen them give my 2 hens and a jake set-up a wary eye and not come close enough. I have heard tremendous success stories about hen and jake sets and bought mine for that reason, but they have never worked for me. Even though I had all my dekes in the truck last week, I only used a single hen. The first gobbler did eye her cautiously, but came in to a few soft clucks. The 2nd one strutted 100 yards away for over 45 mins which made me think the decoy was going to cost me a longbeard. However, a calling sequence timed when he was behind some trees made him come in --I think the cutting was what sealed the deal. I probably will stay with a single hen from now on.
