What am I?

[flap]

This little guy was peering out of a nest box today. I thought the parents were both normal YH. Certainly they are the ones I have seen sitting and feeding. Another little bird appears normal. The one in the picture has light coloured beak, almost white head, and grey/brown splotches on the neck,wings and back. Hard to see while they are still in the nest, hoping it will fledge in the next day or two when we can get a better idea. Other gouldians in the cage are a YH YB female and a dilute male. We did have a normal YH cockbird that could possibly have been split for YB.

Too soon to be certain, but looks more like a yellow than anything from there.

Looks like it could be an Australian Yellow, post more pictures when it fledges.

Thanks for the replies. Two have fledged, one normal. plus the one in the other pics. Here is a new photo. There is another one in the nest, also mottled in appearance, with the grey green mottled colouring around the eyes. Will post those pics once that one fledges.
If it is an Australian yellow, how do they differ from normals and from YB? How can I get one from normals and dilutes? Thanks.

If both parents are split for Australian Yellow then they could produce Australian Yellow chicks, some of the other chicks could also be split for AY but you won't know which ones unless you test breed them later on.

What am I ?

Pretty special!

Definitely Australian yellow both parents will be split AY

Great, thanks. Now to be certain who the parents are... I guess we need to test breed them. We have been trying to get good colored normals, an d have normal and dilutes, wasn't expecting to get a totally different variety...
So now we need to isolate the AYsplits from the normals...
Also we know nothing about AY, just starting to read up on them, so not even sure if having them turn up is a good or a bad thing!

Flap when you say you have dilutes. Are they dilutes or could it possibly be a SF European Yellow cock? Because they have no black and are a type of diluted bird. This is where terminology is a problem. And a SF Euro cock can if I am not mistaken throw a Yellow hen. Pics of the Probable parents might be of help.

WEll I am still not clear at all on that distinction! The probable parents are both visually normal. these are the two birds I have seen sitting and feeding the chicks.
I am not sure how to distinguish between SF Euro Yellow, and dilute. it is all getting quite confusing!!!!
