Broilers grow fast because they need light at night and keep eating, so they grow fast. Many broilers have never seen the sun or touched the ground from birth to death. Broilers can grow to 7~8 kg in 2~3 months, and then they can be sold. The laying rate of broilers in large-scale farms is basically maintained at one a day or even three every two days. ?

Native chickens are usually stocked and exercise a lot. Normal native chickens can live for 7 to 8 years on average, and it takes 4 to 5 months to lay eggs. At the peak of laying eggs, native chickens only have two eggs every three days.

Second, drug use.

What farming fears most is getting sick and infectious diseases. Caged chickens usually use large doses of antibiotics. KFC has completely banned the purchase of antibiotic chickens in the United States. The present situation is that there are still a large number of chickens using antibiotics in China, especially in some small farms.

However, free-range chickens in the mountains are rarely used. After the first three months of growth, they don't need to use drugs. Just like people, their resistance will be strong when they grow up.

Third, meat quality and taste.

Broilers are generally fed full-price feed, and they are kept in cages every day, and they don't exercise. The meat and fat content will be a little more, and their mouths will be full of oil when they eat, and they will be full of meat and oil when they bite, but there is no chicken flavor.

Native chicken is not as fat as broiler chicken, but it has an advantage in flavor. Because it is stocked every day, after all, life lies in exercise, so it has more muscles than broilers, and it feels firm and elastic, and it is very solid. Moreover, native chickens will sleep on time every day, which is healthier than broilers. Kang.

Fourth, food safety.

In terms of food safety, broilers are better. Broilers will be inspected regularly, and chickens with problems will be disposed of, and there is a withdrawal period and security check before they are released.

However, many chickens are stocked, so it is impossible to control this aspect, and it is more difficult to control food safety.
