I have a leading hen, and will likely not purchase any more...
Makes a good upright hen (in which the posture makes other hens want to fight), and take the stake off, it makes a good lay-down hen. Jakes and toms have mounted it...
One decoy, it would be the leading hen. Two would be 3/4 jake and leading hen... Add a third and it would be a feeder.
Mostly my decoys collect dust currently... I am too lazy to carry them around.
