Black-bone eggs, also called green-shell eggs, are called "magic eggs" by Yu Ruomu, a famous nutritionist in China. They are produced by Kuroha green-shell laying hens (Shiquan Chicken in Kuroha, China), and this variety is listed as "National Key Germplasm Resources Protection" project by the Ministry of Agriculture. Beak, crown, hair, skin, meat, bones, toes and internal organs are all black, and there is melanin in the blood. The eggs laid are green (nine black and one green), which has special medicinal value, so it is called "Chinese Kuroha Shiquan Chicken". According to the results of the Institute of Genetics, Chinese Academy of Sciences, Kuroha green-shell laying hens are a valuable specific breed resource, and the rare genetic groups at home and abroad are also unique chicken breeds in China. According to the determination, the contents of protein, vitamins, trace elements and 15 amino acids are significantly higher than those of ordinary local chicken breeds, with low cholesterol content, less crude fat and rich melanin content, which can nourish yin and strengthen yang, tonify kidney and maintain beauty, regulate human functions, and the meat is delicious, thin and tender.

Like a natural nutrition processing factory, Kuroha green shell laying hens are extremely rich in trace elements, vitamins and minerals. They absorb a large amount of these nutrients and transform them into eggs. The main nutritional components in eggs are obviously higher than those in people's eggs. They contain a lot of lecithin, cephalin, vitamins A, B, E and trace elements such as calcium, zinc, selenium, iodine, iron, etc., and Hastelloy unit β globulin in egg yolk. The contents of various amino acids are obviously higher than those of other chicken breeds, especially lysine, glutamic acid and aspartic acid. What is more valuable is that the contents of yolk cholesterol and whole egg cholesterol are about 40% lower than those of ordinary eggs. This is a problem that many experts have not solved through drugs and additives in the past, but now it has been realized due to genetic mutation in chicken breeds. Green-shell eggs are ideal natural health food with high vitamins, trace elements, amino acids, low cholesterol and low fat. The clinical trials of the Affiliated Hospital of Shanghai Second Medical University and the functional experiments of Hubei Provincial Health Department and Jiangxi Provincial Hospital of Traditional Chinese Medicine have proved that they have obvious effects on anorexia, pica, immune deficiency, short stature, cardiovascular diseases, thyroid tumors, gastrointestinal diseases, hypertension, diabetes, insomnia and anti-aging caused by zinc deficiency syndrome in children. It has been approved as "green food" by the National Green Food Development Center and "health food" by the Ministry of Health. Regular consumption can enhance immune function, reduce blood lipid, soften blood vessels, enhance children's intelligence, improve infant dysplasia and anorexia, and improve the nutrition of pregnant women, parturients and patients.
