Very possible, the gene pool is there..!!
Only way to know for sure is to breed from her.

Just looking at this Lutino and Albino bred by Bert Helder in the Netherlands.

Comparing with the hen in this thread leads me to believe tiaris is correct that the bird in this thread is both EY and AY.

Sorry, Craig. I disagree.
A truely pure blue mutation retains ONLY the melanins. These are responsible for the black, greys, browns and, through the spongy layer of the feathers, the blues.
The biscuit colour you refer to is formed partly from the red/yellow lipochrome-style (sorry, I mean carotenoids :)) pigments remaining. If the bird was truely a blue mutation, then these head colours would be white or a shade of grey imo. The backs also have a greenish tinge imo.
Also, you mention belly colour. A true blue bird should have a snow-white belly imo.
Finally, I don't really understand your last point about lipochromes and yellow-backeds having yellow bellies. It is confusing to me.
Cheers
Tom

As for my bird I don't know what I've got there is many possibilities but I don't believe it's a lutino but could well be on to something in later generations.

The above birds are perfect displays of a lutino/albino (to my knowledge there is no single gene albino) but are you all aware that you can also get red head and yellow head Lutino's?

Albino is a combination of a lutino and a true blue. Each mutation eliminates a group of pigments thus you end up with a bird which has no pigment whatsoever.

Because lutinoes retain all their carotenoids, yellow, orange, red are all retained. A lutino black-headed should have a white head unless some carotenoid colour is hidden under the black.

Just a up-date...

She is doing well and has gone to nest (not by my choice) with a BHPBGB possible split blue.
Would of like to had paired her with a DFyWBBH split to nothing.

lol.....im not sure who the expert is.. :think:

She is now 6-7 months old and if it was going to disappear I would of expected it to have cleared up and been completely black by now.

There is no doubt that there is some red still being retained in the eye and even in the shaded part of the aviary you can see it but its a dark red wine like colour and my camera (Iphone 6..lol) cant capture it the way the naked eye see's it.
