I thought she was a self blue (lavender) until the last picture. The last one looks like a dilute splash, and in view of that, the others may also, but it is very hard to tell. If you breed her to a roo that you KNOW is a pure self blue or to one you know for certain is a self blue split, she should have some self blue babes if she's a self blue. If she's a dilute splash, she won't have any self blue babes, but they may LOOK self blue until they get their adult plumage.
