Stupid chicken, Chai chicken and native chicken are called differently in different areas. In fact, they all refer to local free-range chickens. This kind of chicken is generally small, with an adult cock weighing 4 to 5 kg and a hen weighing about 3 kg. White striped chickens on the market are all slaughtered by caged laying hens, and chickens divided into different parts on the market are generally broiler meat. This kind of broiler can grow to 6 in just 40 days after being farmed indoors on a large scale.
