Rainbow budgie & blue series double factor spangle
I tried googling for photos of rainbow budgie. The photos are not specific as it has other mutations, making it really difficult to determine if it is a rainbow budgie.
If anyone has a photo of rainbow budgie, could you post and share?
In addition, I have seen before a violet double factor spangle, an all sky blue violet bird. Since the violet gene is commonly associated with the blue series, would it be reasonable to say that there should be a blue series double factor spangle? Something like an all blue bird? Whether sky blue or cobalt.. Would this be true? If this is true, does anyone have a photo of it to share?
