Just curious on what your idea is on particular traits.
Are you wanting tight/hard sleek feathers, with little fluff, or hard feathered, & moderate fluff?
Tail set, high, low, or mid-set?
Leg length: Normal, Moderate, or long?
Head Size: Large, or small?
Interesting project.
Tip: You're gonna need Orientals, for them to be Orientals, & breed to only Orientals. Otherwise they'd be a homemade breed, or possibly a hardy mix if that direction is chosen.
