What age do polish Roos start to crow?

I have not found a good book on Polish chickens so I'm asking for anyone who might be able to tell me at what age polish roos start to crow. We have had chickens for years but this is our first year with polish. Love them!!

My roosters were late bloomers as far as crowing, 8 months, the hens didn't lay their first egg until 10 months, I already have a new batch of chicks from last year's order!

My white crested black polish roo has started crowing at 10 weeks (this week). He is with 18 other youngsters of varying breeds. None of the other known roos have started crowing yet. They're all 10 weeks old. The others can cluck, but still cheep peep most of the time. The polish roo was the extra chick thrown in by McMurray Hatchery.
