The difference between newborn eggs and eggs in general is as follows: Newborn eggs are fresh eggs that have just been laid from the body of a hen, and their shells are more fragile and are usually smaller in size than mature eggs. There is no significant difference in nutritional content between boring newborn eggs and ordinary eggs, the main differences are quality and storage time.

Specifically, the surface of newborn eggs is easily contaminated by bacteria in the air, so extra care is required when storing, and it can only be left at room temperature for a period of time, if it is left for a long time or encounters high temperature and humidity environment, it will lead to a decrease in its quality, and it is also susceptible to subsequent processing. In contrast, ordinary eggs are subjected to multiple procedures such as shelling and washing, which resist the erosion of the external environment, and can be safely stored for several weeks or even longer. Compared with ordinary eggs, there is no obvious difference in nutritional composition between newborn eggs, but the initial quality is slightly lower, and it is not suitable for long-term storage.
