The reason for that is because the egg of a bird is mainly made up of yolk. Yolk is what feeds and provides the still developing chick with food and other nutrients essential for survival until they hatch, therefore, since most of the egg is yolk, then the chicks that hatch are of reasonably small size compared to the egg they hatched from.
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!
In a few weeks the egg hatch. There parents come back and feed them. The parents leave them. In a 4 weeks the chicks come out and fly away by its self.

Egg incubation helps chicks get out of their shells. Or for the people who have this question as a math problem, the answer is THE EGG SIT (the exit).
The embryo consumes the yolk, and cells turn it into more of the chick enabling it to grow.
They eat, or absorb, the yolk of the egg.
Does It Matter? but there are little holes in the egg
chicks could come from both roosters as the hen stores sperm and releases it drop by drop as each egg is ready for fertilisation
For farm chickens, they often get table scaps right from the very start of their foraging. Chicks follow the brood hen out and around the yard and are eating whatever she is. If you know you have chicks in the yard, just cut your scaps tiny so the chicks have a chance at them.
No-one ever sees the egg. It is way too tiny.
no
you hatch eggs to grow the chicks into chickens for their meat and eggs to eat
