I have a 20 month old BJG. He doesn’t crow a lot - many times a day, but really not often. He has a deeper crow than other males. Loud, but not that ear splitting note.
Tha dark brown leghorn males wouldn’t shut up and they were loud. We got rid of them around 5 months and I did not miss their crowing - it was annoying. They were colorful and attractive though, so definite plus for their very rooster-like appearance, and great tail feathers.
we had a talkative and loud Black Copper Marans, but hormonal and aggressive do we sold him at approx 5 months.
We had a BA, not excessive crowing but more than the BJG. Loud, clear, good crowing.
had an EE- never crowed.
currently have 2 Dorkings, but they are just hitting puberty, no crows yet.
