Do you know the secret of the 'number 4 egg'?

Here are three hens living in a small chicken coop.
It's so cramped that they have to push each other around and it's hard, but there are happy moments for them too.
This is the moment when eggs are laid.
But one day, the chickens realize that all their eggs are number 4.
Why are all eggs laid by chickens numbered 4? Do you know the secret behind the number 4 egg? "The Secret of the Number 4 Egg" delightfully depicts the process by which three hens, more dedicated than anyone else to laying eggs, uncover the secret behind the eggs they lay.
