chicken maturity?

[watchdogps]

I'm trying to figure out what ages correspond in chickens as far as maturity? Like, what age is considered "adolescent" and when are they adults? How "old" is a 6 weeks old? It seems all I see are chicks and adults..

I never really thought of it.

They are pullets or cockerels until they reach one year old then they are hens and roosters. They are fairly mature when the pullets start laying around 4 to 5 months.

Understand this is just my personal opinion, and I do not know if there are specific timelines, so someone please correct me if you know.

Chicks: Hatch to 12 weeks. (Children)

Pullets: 12 weeks to 20 weeks. (Teens)

Layers: 20 weeks to one year. (Young adults)

Hens: Over one year. (The rest of us)

Anyone have other ideas??
