* Gas Exchange: The tiny holes allow for the passage of oxygen into the egg and carbon dioxide out. This is essential for the chick's respiration as it grows.
* Moisture Regulation: The pores also help regulate the humidity inside the egg. They allow some moisture to escape, preventing the egg from becoming too damp, while also preventing it from drying out completely.
* Shell Strength: The pores are actually tiny channels that connect to the inner shell membrane. This network of channels helps distribute stress throughout the shell, making it stronger and less likely to crack.
In essence, the porous eggshell acts like a tiny breathing apparatus for the developing chick, ensuring it receives the necessary oxygen and maintains a suitable environment for growth.
