The calcium that makes the egg shell makes it hard.

If you put a fresh uncooked egg into vinegar the hard shell will dissolve leaving just the soft membrane.
Yes. Bird eggs are similar in structure to reptile eggs with the main difference being that bird eggs have a hard shell while reptiles eggs have a softer, leathery shell.
no.
No snake does unless scientist fond another specie is found .
eggs have a hard shell that keeps it from drying out
Reptiles, such as turtles, snakes, and lizards, produce eggs with a leathery shell. The leathery shell is flexible and allows the eggs to absorb moisture and exchange gases with the environment. Unlike reptiles, birds and some other groups of vertebrates produce eggs with a hard, calcified shell.
All eggs that have a hard or semi hard shell are fertilized before being laid.
it is because egg shell contains calcium and this what makes it white
Yes, it does DEFIANTLY! cockroaches lay there eggs with hard shells, as it easier for cockroaches to reproduce.. .. HOPE IT HELPS! :) :) :) :)
It depends on how fresh they are. Eggs that are very recently laid will often have the white stick to the shell a bit.
NO- the vast majority of the commercial eggs are infertile- the hen never sees a rooster. Fertilization of the egg happend BEFORE the shell membranes and shell are added. Fertilization is not needed to form a shell.
All bird eggs are hard, there is no choice. Ones without a proper shell are defective and usually won't hatch.
