Some are noisy....but I've noticed that they will be more vocal when there are a few extra Roosters...ends up as a crow off...stress will cause more crowing....it's spring! They find that something to crow about...it sounds strange, but I can tell my Roosters that I've had enough! And it's time to shut up! Sometimes it seems to work! If they get to carried away at watering time....I've cooled the vocals with a quick squirt from the hose...use the same technique on my big white rock roo, when he decides to test his luck...and forgets who's in charge....I don't want a 12 pound rooster spurring me. Usually he grabs my pant leg and tugs on it like a dog....but if he includes the feet...he gets hosed. Sorry got away from the original question. Stress, spring, hormones, you name it...all reason to crow. They seem to quite down once the pecking order is established.
