Be aware that, in general, they seem to be a 3 year hen. I feel that Tsuki is mean and ornery enough to live much longer but I believe she is an exception.
But for laying you can't beat them. If you are looking for consistent eggs they can't be beat and will actually turn over your flock for you because they are not long lived.
They have big personalities and are tons of fun but they may not stay long. I no longer have them because I need my pets to be like Lilly and stick around longer than that. I get too attached. But I adore everything else about them.
