I'd put up the hen decoy with the Funky Chicken...
Looking at his first bird, I am assuming he will flop a jake if the opportunity presents... I think that the full-strut pose would be more apt to scare off less dominant birds than the "Funky Chicken."
That Funky Chicken looks absurd to me, but out of everyone I know that uses one, I have yet to hear a bad review as far as results in the field...
