We only have one rooster. My next door neighbor isn't thrilled with him, but he doesn't mind him. I'm afraid if I get two ducks that he'll start complaining about the noise. Just how loud are they? My rooster only crows in the morning when I let the dogs out, in the afternoon when I get home from work and let the dogs out again and usually in the late afternoon when he and another neighbors roosters have a crowing contest.
