What age do cockerels/roosters start crowing?

[Ezio]

I have a six month old (I think) bantam cockerel who has never even attempted to crow. He says "HA HA HA" or else sounds like a hen about to lay an egg.

He reminds me of the Family Guy sketch where Stewie is playing with the european see-and-say and the rooster goes "dickery-dickery-doo".

Here is a pic of him, what breed would you say he is?

Minorica Bantam.
