I think he is a roux dilute, but I'd love to see his back. Roux dilute + italian = autumn amber. So once you have one it's easy to get the other although it's important to note females take two copies of roux to express so it will require some back breeding to get roux or autumn amber hens.
As long as they have some space to get away they won't *kill* each other, but expect some scuffles. Also, once you separate brothers they do not enjoy going back together.
Geez, I didn’t realize quail genetics were as confusing as pigeon genetics.
