My dear BLRW roo, Crimson, has lost his voice. He seems healthy, alert, active, and puzzled and frustrated. Our noisier roo crows a lot, but Crimson can now only make a quiet squeaky noise. He cannot even cluck. His voice started out hoarse last week, and now he sounds just like I did when I lost my voice-air is the only thing coming out. For a few weeks, maybe as much as 2 months, he has occasionally made a prolonged, high-pitched 'scream' which seems intentional. He would stand very tall and perfectly still and whistle like a tea kettle in the other room. How he had enough air to carry on so long I still don't know. The others would ignore this, mostly. He was still making as much 'normal' noise as ever when he began this. I am puzzled. I don't mind him being mute- I didn't mind him crowing either- I am just worried about him. I like him, and want him to be ok. Is there anything that can cause a rooster to go mute that I should worry about? Like I said, he seems fine otherwise. Everyone else is ok too.
