they come in both large fowl and bantam, i have LF and they have decent laying although they are a medium size egg. temperament? it takes them a while to warm up to anyone, even as new hatched chicks they are very skittish even when regularly interacted with and handled, they don't really grow out of it either till they are nearly fully mature, they are very playful (with each other) and they are quiet till they decide to open up then they are chatter boxes, the only thing i wish was different about them is the being skittish, they are beautiful and i enjoy having them but they aren't lap birds by any means.
