So I have a Rooster, actually I have two, one has established dominance and for the most part they get along. However, the one Rooster doesn't crow at all, never has, he tried one day and it was the worst sound, but he never did it again. He does go through the motion of crowing, he opens his beak and dips his head like he is crowing, but no sound comes out at all!!! Is this a normal thing?
