Well, my Black Orpington rooster has finally started crowing at six and a half months old! His crow is in a rather low pitch and not very loud. He is my first rooster, so I am wondering if this is how his crowing will always sound? Or do roosters' crowing voices change over time as they get more mature? I really like the way he sounds now but if it changes i'm ok with that. I do like the fact that his crow is not high pitched and shrill! I welcome comments by people with more rooster experience!
