What is the chance of you finding an egg inside another egg? Apparently one in several million eggs, and one lucky housewive actually came across such an “egg-citing” discovery.

This egg within another egg was bought from a normal supermarket in Kyoto recently.

According to a spokeperson from the poultry research division at the Gifu Prefectural Livestock Research Institute:

“It seems to happen more when chickens get stressed”.

During the egg production process, it is not unheard of for a partially developed egg to flow back into the chicken’s ovarian duct and then become covered by another shell as the process continues on a new egg.
