Yellow goulds

[bernd76287]

Hallo!
I read an interesting article about the colors goulds can have.
A 2 factor yellow cock has lost the blue color and also all phaemelanin and eumelanin. This is right!?
Sometimes it would be possible that a bird occurs , which hast only lost the blue color. See my painted gould. I think it must look like my picture.

I found a female under my birds with yellow-green feathers on the back. The yellow belly is very intensive, nearly orange. What do you think . its normal?

I have never heard of a yellow gouldian that had masked structural blue but could still fully produce melanins; the two go hand in hand.. the reason why the blue is masked is because of the melanin suppression.

The only real "exception" would be a SF Yellow male which only partially suppresses the melanins; but they still cannot fully manufacture them.

I don't see the yellow on the back feathers at all of this hen. She just looks like a normal green back to me
