Idk. Look up the pumpkin pied. Wait, orange instead of white? No. The white is from partial leucism. No pigment whatsoever. That would override whatever orange color/gene you have in mind, though the patterned part would be affected.
Holy crap those are sweeet! I would definitely get one! Both, if I could!
How the heck did he get them? If they're from the same clutch, I'd think there was something special in their genes. Imagine if it does turn out to be a super low white line. You'd have something really special there.
