I see places where ducks, and even some chickens, appear to be out in the open, around a pond or a farm without ever running off. Is this typical, or am I missing some thing? Reason I am asking, is that my lot is about 75 yards from a big public lake. Would ducks possible split their time between the lake shore and the duck-coop if they were regularly fed near the coop? Do ducks go feral?
