I'm not saying all Buff Orpington roosters are quiet, but I have to say, mine is remarkably so. Stumpy has avoided becoming Stew because he's so quiet. He crows, but never at night, and only a few times during the day - as a matter of that, I was out there most of the day yesterday and he never uttered a peep. I have heard him, around 7 am, crow once or twice, but that's about it.
