When does a rooser start crowing?

[my peeps and me]

I have 2 Golden Comets age 15 weeks, 8 easter eggers 14 weeks and 2 Buff Orpingtons that are 12 weeks. I am concerned one one of my orps is a rooster as it is larger that the other one. Should I know by now if I had a rooster? Wouldn't it already be crowing?

My Americauana rooster (Fluffy)started at 12 weeks old.

So hopefully my golden comets and easter eggers are all hens. I will just need to wait a little longer to see about the orp.

Usually around 4-5 months. Rarely, certain individuals will crow as early as 2 weeks.

Both my roosters started crowing at 10 weeks old ... one a Dorking, the other a Buttercup ....

all of the roosters I have ever had started crowing between 6-8 weeks...I have had old english games, Easter eggers, polish, silkies, and many more and all of them started between 6-8 weeks old
