A rooster crows for a reason. IMO, it would be useless to have a rooster that couldn't alert his flock. (I live where only hens are allowed, and have to take the necessary precautions for their protection. When life offers the opportunity, I'll retire to where I can have a loud, crowing rooster to do his job and protect the flock). -can't imagine a poor rooster without the ability to crow and do what nature intended.
