Go to Hawaii, the island is riddled with wild Chickens, the joke is that the Chicken is the state bird.
A wild turkey and a domestic turkey differ primarily in intelligence. Wild Turkeys are smart and cautious. Domesticated turkeys are about as stupid as a really smart Liberal.
But, all else aside, no Chicken - wild or tame - has the body mass to wing ratio for any significant flights. You will never see the Great Chicken Migration of 2009, Chickens are just not built to fly. Far too much mass.
I’ve had yard chickens that did pretty good. My neighbor raised peacocks and those suckers were scary, they couldn’t turn very well. You just had to duck!
