Yes. Most blue birds (besides self blue, whole 'nother subject) come in blue black & splash. Her official title would be Blue copper Marans, but she is the splash shade of blue. Beautiful! Bred to a black rooster you'd get 100% blue chicks. But blue bred to blue yields 50% blue, 25% splash, 25% black.
Sorry, too much info, just thought you might like to know.
Breeding and genetics really sparked my interest last year, so I try to share some of the easily understandable bits.
One of my favorite birds was a blue copper marans, she was so pretty, so confident and clever.. Marilyn. Yours is gorgeous.
