It depends on the species of birds.
I think the word you are looking for is - an egg!
It is a bird. A bird hatches from an egg.

A baby king cobra is usually at least 18 or 19 inches long when it hatches, and fully prepared with deadly venom. It leaves its nest immediately and cares for itself from then on.
It either hatches and a baby bird comes out, or the egg rots.
unfortunatly the bird could (could not yes) die. im sorry.
Yes, there is one that i know of. The Cuckoo bird lays its eggs in the nest of a host bird of another species, usually one with similar looking eggs to its own. The host bird then looks after the egg as if it were its own offspring. When the baby Cuckoo hatches, being bigger, it then pushes out the host birds real nestlings, usually making itself the sole offspring of its surrogate mother. It stays in the nest until it is ready to head out on its own and the surrogate feeds and cares for it, regardless of the fact that it has killed her young and is often much bigger in size than she is herself.
no one cares!
Well, baby chickens are yellow, but most birds are just grey when yhey are newly hatched.
A killdeer lays these eggs but they can sometimes be blue with brown spots
