Rooster crowing at 7 weeks?

[Spear1]

I hatched 4 chicks from supermarket eggs on 22nd January and one of the 4 is a rooster. He is really beautiful and starting to crow already! Is it normal for rooster to crow this young (7 weeks)?

Roosters usually crow at about 5 months but I have had some start as young as 7 weeks. It is just down to the individual bird.

He looks like he's got a big attitude already too.
Fayomis mature very early. My one cockerel started crowing at 28 days! He'd throw his little head back and let loose, with his little stubs of hackle feathers barely starting to come in. Too cute!

I've seen video of a cockerel trying to crow at a week old. They do it when they're ready to establish a territory.
