That is crazy, Mahonri! Would've thought you'd get that color? Cool chicken.
I think, in * theory *, you would get solid blues and blacks from crossing your blue with the gold laced--though they'd likely have some red/gold leaking through, and you wouldn't want to breed the offspring with the intent of breeding pure blues/blacks (I imagine they'd throw some "surprises."
). Someone correct me if I'm wrong. Regardless, like everyone has already said, you'll need to separate your varieties to keep them pure.
There are some varieties you can run together, though, depending on how you have your breeding groups set up. What different colors do you have? Right now, to save on pen space, I have wc black, blue, and chocolate cuckoo hens with a wc black rooster. Sounds like a muddy mess, but it's not--all varieties will be pure from this pen, because all of the hens are of colors that can be bred to black. So from this pen, I can get wc black, wc blue, wc chocolate, wc cuckoo, and wc chocolate cuckoo offspring.
So, you may find that you have color varieties that can be bred together and kept pure, if pen space is an issue.
