Decoys have found their way into most folks vest these days. I'll tell ya'll a story about a homemade dek one day. It's a hoot!
I started carrying a single hen many years ago, then added a jake. Now and have been successful for some time is a three decoy set up. It consist of a jake, 1 up right hen and 1 feeding hen. I set the upright hen at about 25 yards ,with the jake several feet directly behind her. Then ,off to the side at about another 20 yards I place the feeding hen. It gives the approaching gobbler the idea that at jake is about to breed the hen. Nine times out of ten, the gobbler will march right pass the hens and get eyeball to eyeball with the jake....... At that time, it's bye bye
