Everygbody has their own favorite set-up and mine is 3.
3 hens one at atention the other two feeding spaced about 6 to 8 ft apart. Do not group them. or I ahve used the Strutting Tom decoy in place on one hen and then a hen is palced directly on the ground in front of him. I have had very poor success using a Jake decoy.

Then at times I use one hen or no decoy at all. Depends on what style of hutning I am doing and how much other hunting pressure the birds I am after have undgergone.
