It's just a guess, of course. When there was demand for readily available cut-up chickens in the meat case..folks could expect to pay more for the convenience....and some merchants would gladly take advantage of that. Times have change. Preferences have change. Meat departments have changed. It's not just cut-up chicken...fresh game hens, broilers, chickens cut in half, gizzards, necks and more are things that were available in the meat case years ago but are impossible to find now....in this area anyway. If one is lucky to have a good butcher in the neighborhood, they'll gladly cut-up a chicken at no extra charge.
