All I can say is that the coloring will be unpredictable......I've never done it so I guess all you will get is a mutt. Maybe a pretty mutt, but a mutt none-the-less. Good luck!
You can't predict what the outcome will be without knowing more about the genotypes of the parents. Each chick will only get half of each bird's genes, and unless each is homozygous for each gene, there's no telling what will happen. I'd like it if someone could compile a list of the results of unusual crosses, so we can all compare notes!
