Chickens basically hatch in eggs, but they fail to break their shells and die, and then people steam the eggs they eat.

Hairy egg refers to the immature chicken being destroyed unintentionally or intentionally during the incubation process, which leads to the stop of chicken embryo development and death in the eggshell. Hairy eggs are also called live pearls, because the blastocysts of fertilized eggs are shaped like moving pearls in perspective. Hairy eggs are usually cooked, plucked, dipped in sauce and washed before stewing.
