How broody are they, say compared to a Silkie? How's the rooster's crow? How about the rooster's temperament?How large are the eggs compared to other bantams? I have one bantam Cochin, no others, but I'm fascinated with the Porcelain D'Uccles as a possible second variety of bantam. My DH loves Shadow and if she could have a couple of pals in their own coop, well, you see where this is going. I need more input, though.
