What do you call those eggs anyway?

Ever wonder what a bird's eggs are called other than an egg? Or what to call a baby bird in the nest other than a baby bird? Or what exactly is a fledgling? Well, here the scoop:

Fertilized eggs in the nest are a clutch.

Newly hatched babies are hatchlings

And when the feathers start to appear they are pullets or cockerels.

And when they get their flight feathers they are called fledglings.

After they actually have their first flight they become Juveniles.

And usually after a year, or when they mature, they are then adults.
