I've got 18 cocks and stags on the place at the moment, all in seperate accomodations. Thirteen of them are crowers...the others will be soon. However, my neighbours (the nearest about 1/4 of a mile away) are all country people born and bred. On a quiet day, they can be heard up to two miles or so from the house. Other days, depending on the wind strength and direction, you'd hardly know I've got them.
I hear them through the night and day because I am listening for them, but the rest of the family seem not to notice.
A cock is a good thing for a flock of laying hens, though, as it allows the hens to feel secure as they forage. The cock's nutritional needs are not so great as those of the hens, so he spends his time flapping his wings, parading about, crowing, and watching for danger.
Some of my game cocks have been known to put foxes to flight in defence of their flock, but others have lost their lives as a result of their devotion to their hens.
