I learned on here that Sky is a sky blue recessive pied female.. when I first got her, her body color was all white except for the lower belly which is blue and her mask feathers were yellow. After her first moult since I got her, her mask feathers got brighter and the yellow diffused through all of the white part of her body but the blue of her lower belly didn't change..so she couldn't be a YF type 2? but if she was a YF type 1 then the yellow would only be on her face and in the peripheral tail feathers am I right?

 

So is she a yellowface or not? and if she is not then how come that all of the white part of her body is now a yellowish white? This is so confusing

 

 

 

This an old picture of her.. now the white is yellowish and her mask feathers are a brighter yellow.

I think she is a yellow face not sure I'm not good with recessive's

She is a type 2 yellow face recessive pied. The yellow doesn't have to spread all of her body feathers to show which mutation of yellow face she belongs to

i am with neville

She is likely a Double Factor yellow face type 2. I have not yet bred them myself, but from what i've read im pretty sure it results in the yellow spillage being refined to the chest area instead of all over the body as it would in SF YF2.

i agree with neville

yes a yellowface type 2 the fact that the yellow as bled into the chest feathers proves that, a type 1 would have no bleeding of all into the body.

 

as the bird ages you could get more of the yellow appearing in the body feathers.
