I plan on hunting merriams this year in Colo.  We have few turkeys and lots of country to hike (5 to 10 mile hikes are common).  I'm trying to figure out a jake/tom decoy that doesn't tend to take up a bunch of room and is lighter weight.  I can think of a couple options.  One would be a funky chicken.  The FC is one of the craziest decoys I've ever seen!  Has anyone had very good luck with them?  Another option I'm considering is a thunder chicken with a real fan.
