He just really likes to crow. Crowing isn't inconsiderate in the eyes of a rooster. Chickens don't think that way. He isn't trying to get on your nerves or the nerves of anyone else, he's just telling the world that this is his territory and those are his hens and that nobody will get away with attacking them. Do you hate the crowing? Do others around you? Has he ever spurred your daughter? How is he with the hens? Does he warn them of danger and lead them to food and such? Has he attacked any predators to ward them off? You have to ask yourself if he's worth it, despite his crowing. If the answer is no, give him away, if yes, learn to love him in spite of the noise. If you don't have any close neighbors and you don't hate the sound of crowing, what's the problem?
@hysop has a good answer. Some roosters crow more than others. Some crow for food. My mother's crow when they see us and when they want to eat worms, they also crow in the morning. And there's three of them so they crow back and forth for a while. They do stop crowing after a while and then only crow occasionally, (more if we're out there). Also, all animals tend to mellow out as they get older. He may just be in the hormonal teenage years.
