Crowing hen and young cockerels

[nuthatched]

Hi all,
I have a hen that crows every morning a few times, not loud, not well but she's enthusiastic, and two cockerels (I think) about 11 weeks old.
I'm wondering if the fact that there's already a crowing bird will have any affect to keep the young ones from crowing, since a dominant roosters will discourage the other roos from crowing.
Or since they know she's a hen and not a rooster, they won't be affected at all?
I was expecting to hear some squeaky, gung-ho crows by now.
Thanks.

I think that eventually the males hormones will reign.
Tho that crowing hen may be keeping them in check for now,
but then again not all cockerels crow so young.
