You need to crack it open then measure the outside of it with a ruler in millimeters. OR you could use a micrometer.
the egg's shell is not that thick like the crust, the egg white is the thickest like the mantle and the yolk is thick like the core
the shell of an egg
The thickness of the shell is not determined by the color. The age and health of the bird determines the quality of the shell. As a hen ages, her reproductive system cannot maintain peak shell making capabilities. Her system will no longer utilize the proteins and calcium she eats the same as when she was young. Eventually her egg production comes to a halt.
The shell thickness and texture changes with the vitamins and minerals the hen receives. That is why that if an egg gets broken they will consume not only the egg but also the egg shell. In the past farmers would save their egg shells from the kitchen, dry them out and crush them to be fed back to the hens.
This is an egg that can be in a shell and out of a shell.
the shell of an egg
is the shell of a hen egg as brittle as the shell of a duck or a goose egg
If the shell was too thick, it would not allow for the gas exchange required to maintain life for the chick, and indeed the shells of larger birds such as emu, kiwi, etc, do have very conspicuous pores. The bird only makes the shell as thick as it is needed - a larger eggshell needs to be stronger to withstand the greater forces of its own weight, and minor impacts. Perhaps you could measure the thickness of a small bird's egg shell, and compare that to a chicken, and have a look at an ostrich egg in a museum. Be a scientist.
egg shell
its thickness can be measure in mm(milimeters)
A leathery shell is a shell that is flexible rather than solid like the shell of a bird egg. A snake's egg has a shell that is flexible, as does a turtle's egg.
