Native chickens are completely free-range, go out every day and find their own food. The eggs laid by this kind of chicken are native eggs, which are smaller, but their yolks are larger and darker, and they are high in carotenoids, vitamin B2, cholesterol and fat. Because cholesterol is the main component of cell membrane and the precursor of steroids, vitamin D and bile acid, it has extremely important physiological functions, so it is more suitable for children to eat.

In addition, eating 1 egg yolk a day will not cause a rise in blood lipids, so for friends with high blood lipids, high blood pressure and coronary heart disease, eating foreign eggs will be more appropriate and economical.
