White Rock x Blue Breasted Brown Leghorn

[Allthebirds]

I'm thinking of breeding my White Rock roo over a few Blue Breasted Brown Leghorn hens. Can anyone help me predict to color/pattern of the offspring?

It's hard to say but since white Rocks are usually genetically black barred under the white, and blue breasted brown looks like a cross of blue and brown leghorns...
You'd get blue barred and black barred chicks. Daughters would have silvery white leakage and sons would have yellowish leakage.
