Blue Orpington Roo X Light Brahma hen

[tjessen]

Does anyone know what kind of colors this cross would produce?

You should get about half solid blue and half solid black. The Blue Orp should be split for the B/B/S gene so half his chicks will get blue, half will not. He should be based on black. The Light Brahma is Columbia so the black from the roo will override anything she contributes. You might get some leakage (a random feather a different color) but basically solid black or solid blue.
