Does anybody include the sound of the crowing when you decide which cockerels to keep? As if I need one more thing to worry about---but some of these black copper marans have the most long, drawn out crow. Is the way they crow hereditary? My founding cock has a long drawn out crow, and so do some of his offspring--at least the dominant ones that are crowing. I'd like to keep one whose crow is a bit shorter for the benefit of my neighbor, but I don't have a whole lot left to choose from.
