I have the same problem. He mad a noise that was just horrible and sounded like something was dying and my neighbor heard that. Then Monday my neighbors heard him crow again.
I have a rooster which is about 14-15 weeks old. I have him in with 3 hens and a bantam rooster. My neighbor has 3 roosters the same age as my young rooster and his are crowing however my young rooster will not crow. Does anyone know why? Possibly because of the bantam rooster?
