Question

Why do we need eggs to crack?

Answer 1

Most likely, you are cracking the eggs against something and you are not able to control the momentum of your hand and arm. If you insist on doing it this way, such as cracking against the edge of a bowl, consider a gentle wrist action to gently crack the egg without a lot of follow through that will damage the yolk.

Answer 2

We need them to crack so that chicks or any animal that cracks from an egg can get out without having an immense struggle
