Chickens did not hatch from fertilized eggs within 14 to 2 1 day, and "hairy" eggs were formed from dead eggs. People call it "hairy egg", and some places call it "widowed egg". Causes of few eggs: Sometimes it is due to temperature and humidity, and sometimes it is due to bacterial infection.
The reason why few eggs can't be eaten:
1, according to the test, almost 100% of the few eggs can be detected with Escherichia coli, and some of them have also detected staphylococci, typhoid Bacillus, Proteus and so on.
2. Nutrients such as protein, fat, sugar, inorganic salts and vitamins contained in eggs have changed during the incubation process, and most of the nutrients have been consumed by the development of embryos.
3. Oligoeggs contain physiologically active substances (such as estrogen, progesterone, etc.). Children who eat them often will cause endocrine disorders and lead to precocious puberty.
Because few eggs can't be stored and transported according to reasonable hygiene requirements like fresh eggs, it is impossible for vendors selling few eggs to clean and disinfect them. If you don't pay attention to eating that kind of heated and polluted hairy egg, it may cause digestive tract diseases, such as abdominal pain, diarrhea, nausea and vomiting.
Because from the point of view of nutrition, the nutritional content of "few eggs" is not higher than that of fresh eggs, and if the embryo dies for a long time, it will also produce harmful toxins, so it is better for adults and children to eat less and not eat few eggs.
