Hatch a few and see what you get! Can't hurt...and if you improve type you can always worry about getting out off colors in the next generation...
Thanks Linda. I've heard it can take 3-4 generations of crossing back to black to get rid of the champagne off-color in paints, so it's probably not your roo. My guy has more than just a little leakage though- he has a flood! But came from 2 black parents. And otherwise is a wow bird. What to do what to do....
