Chickens or ducklings that are not hatched are commonly known as "hairy eggs", also known as stillborn eggs, which are immature fetal eggs that are affected by improper temperature, humidity or some germs during the incubation process, resulting in the embryo development stopping and dying in the eggshell.

As a matter of fact, most of the nutrients such as protein, fat, sugar, vitamins or minerals contained in hairy eggs have been used by embryos during the incubation process, so they are not of much nutritional value and cannot be compared with fresh eggs at all. Moreover, hairy eggs may also contain Escherichia coli, Staphylococcus, Salmonella typhi, Proteus and other germs. If people eat this kind of eggs with germs, it is easy to have food poisoning and induce diseases such as dysentery, typhoid fever and hepatitis. In addition, the hormone content in hairy eggs is high, which is extremely unfavorable to the growth and development of teenagers.

According to the detection, Escherichia coli can be detected in almost 100% of raw eggs, and some of them have also detected grape coccidia, typhoid Bacillus, Proteus and so on. Moreover, there is a problem that cannot be ignored here, that is, hairy eggs can't be stored and transported according to reasonable hygiene requirements like fresh eggs, and those vendors selling hairy eggs can't be cleaned and disinfected, which shows that the hygiene situation is really worrying. If you eat that kind of heated and polluted hairy egg; It can also cause digestive tract diseases, such as abdominal pain, diarrhea, nausea and vomiting.

There is also a kind of hairy egg, which is a live fetal hairy egg. That is, when chickens hatch, they intentionally stop hatching and form live fetal hair eggs. Because of the delicious taste of live fetal hair eggs and the unique nutrition of half eggs and half chickens, it is also a good food. On the other hand, it is not worth the loss to produce this kind of hairy egg, which is very rare in the market. Therefore, we should see 100% dead hairy eggs.
