this is my first time having a cockeral on the cusp of roosterhood. So I couldn't tell you of a standard, but my roo started crowing as soon as it was fully grown and feathered. At first he only crowed once or twice at sun up, and now he crows about 10 times a day. Also, for what i've heard from local poultry folks is that roosters that are confined crow much less then free range roos.
