Lurking
Each bird is an induvial and matures differently. There is no "normal" time for him to start crowing. Some will attempt to crow at just 6 weeks old, some won't start till they're 20 weeks old. He'll crow when he crows.Any idea to why he don’t crow yet?
If you have more higher-ranking roosters in your flock the lower ranking boys may not crow as much or as often because the other males will bully him.
