they use their beaks to crack it open
A developing chick nourishes itself inside the eggshell through the egg yolk. This is the chicks source of food.
They have an "egg tooth" on their beak that they use to crack the eggshell when they are ready to hatch.
Hatching is the process in which baby birds (called chicks) come out of the egg they are born in. The chicks have an egg tooth that they use to break out of the egg. Once the chick has broken the eggshell, its egg tooth will fall off. I hope this helps!
