If you breed her to the Runner the babies will be sex-linked. The girls will have the buff gene and be similar but lighter to my lavender but with spotting like an Ancona due to the runner pattern. The boys will look similar with the same spotting but blue (no buff will show). Here are some of mine from my silver crested:
This is right after hatch and you can see the girl on the far left has a brownish tint. The boy on top of her, showing his whole back, is blue.
Same group a day or two later. The 2 girls on the right, the 2 boys on the left. Ignore the duckling with the facial stripes and back spots, she had a different mother.
Same ones mostly all grown up.
Female that I kept from a different hatch (same parents).
This a a Dutch Hookbill drake I hatched (there was some outcrossing a few generations back). He is blue with the runner pattern. I suspect this is what yours would look similar to.
Same one a few weeks older.
Same one all grown up. I didn’t keep him. He went to a friend and this is the only photo I have of him grown.
I look forward to seeing what you get.
