I have a silkie rooster. He is loud and crows a lot AND I live in suburbia where roosters are not allowed. So he wears a rooster collar which quietens his crows to about 25% of the noise level and at night he goes into my laundry so that when he starts crowing at 6am he will not be heard. So you can definitely keep a rooster in suburbia if you are prepared to put in the effort.
