Not all Jakes gobble or display. Jakes will be in packs at this time of year as they have been shunned and chased off by the mature Toms.
Jakes may attack decoys en mass and can be very aggressive as a pack or complete panzies!
Bad thing abouy Jakes ~ they come to calls quicker than Toms do and when they see something they don't like ~ they leave just as fast too. And if they have been a satelitte group, holding on the fringes of a nice Tom and his harmen of hens ~ Well when the Jakes leave - they help pull that Tom away from you. See it many times......
