Factory produced free range chicken

Why are free range chicken popular? One of its touted plus point is it is supposed to have more muscles and less fat. This is because the chicken exercise more and spend less time coped up in the cage inactive. Well, here is an amazing invention - factory produced free range chicken! This is the conventional poultry farm with a slight modification. A conveyor belt replaces the floor of the cage. Every now and then, the conveyor belt moves, forcing the chicken to ambulate and thus get some exercise! And there is a plus point. Add a scrapper at the end of the conveyor belt to scrap off chicken poo and you have without additional labor help collect environmentally friendly natural fertilizer.
