5 stages of chickens life? - Help with a project

[call ducks]

So i have to crate a PP for an ag project about chickens and giraffes(why we have to do an exotic animal i have no clue) i had it all done than the computer crashed and i needed to reformat!

So i am trying to remeber the 5 stages of an animals life.

It's

Birth

Adolescence

??? (something) (reproduction?)
??? (something) (aging?)
Death

Anyhelp? the notes about this were on the computer and the teacher is less than happy about my notes being lost!

you're forgetting when they are in the egg. Chickens are growing inside the egg, so that could be a stage

Or another stage could be when they're younger, like a child
