It is the same as a regular chicken shell.

The zona or zona pellucida is the thick protein shell around a human egg. In order for the egg to become fertilized, the sperm has to break through the zona.
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.
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

It takes exactly 8 weeks for a emu egg to hatch, & they should be incubated at a steady temp of 96-97 degrees. If incubated at a higher temperature, the chicks will have trouble getting out of the egg. This is because the egg shell hardens.
I just bought an emu egg from an emu farm. The owner of the farm told me 1 hour and 45 minutes to hard boil the egg.

an adaptation it has is a thick shell or something like that
From the outside in we have the: blume- a water proof coating to protect the shell The Shell outer shell membrane inner shell membrane thin albumin or egg whites thick albumin or egg whites the chalaza that looks like white cords that run from the eggyolk through the egg whites at both the top and bottom of the egg an egg yolk and on top of the egg yolk the germ disk.
