The difference between white-shelled eggs (shiratama) and brown-shelled eggs (akadama) depends on the breed of the parent hens.
The chickens raised at Tategamori Ark Farm are a breed called Nera and produce red eggs.
However, some may lay eggs with whitish shells.
Differences are said to be caused by individual personalities, differences in living environments, etc.
For example, chickens that live in a well-lit part of the chicken house for a long time are more susceptible to predators.
It is said that they lay pale (whitish) eggs to make them less noticeable.
