I have a 18 week mix of something that I thought was a hen. I posted his picture on the breed thread to find out his breed and was told he was a boy. We had one other banty rooster out of this batch that started crowing over a month ago (just about 3 months old) and went to live with friends in the country. This one has never even made a peep or given any hint of rooster noise. Is that normal for a rooster of his age or are we just getting lucky?
