Bigger doesn't necessarily mean better. Flextone's Funky Chicken® proves this with an abnormal shape and smaller size that triggers aggressive gobbler behavior during spring mating season.
While full-body strutting decoys look good, they also look like a turkey that might be able to win a fight. The Funky Chicken doesn't have size on his side; he's the skinny, wimpy kid that every turkey knows he can beat up. This easy target is non-intimidating to both passive and dominant gobblers. It's a disadvantage for the Funky Chicken, but an advantage for you that will bring in gobblers looking for a confidence boost.
So this turkey season, give them something to pick on... and then pick on them. Get funky with the Funky Chicken.
