Since you have gotten gold birds from them and I think you said something about partridge, that would be a good side project. When I had dark brahmas a few years back I tried to make partridge brahmas by using a partridge rock cock on dark brahma hens and I got a trio of chicks, I sold the pair to a friend that wanted to work with them and gave the other hen to a friend that wanted her for a pet. The pair got killed and the other hen was bred with a gold laced cochin x dark cornish cross and had some amazing chicks that look like a partridge brahma.
Blue laced red would look awesome too.
