Good question, I never really compared the volume of crows. That little bantam crowed a lot when hew was in our garage. Because they were small, they stayed much longer than large fowl chicks would have and it was his crowing that made me move them from the garage. So, bantams can crow pretty loud too.Great! If I can get a big piece of lot, I may just take a couple lavender ameraucanas. I always wanted them, but I wasn't allowed to have a roo. Is a bantam roo less loud?
