If they are Australian Yellows, which it seems they are from those photos, then both parents are split for AY. Normal/AY + Normal/AY will yield on average 1x Normal, 2 x Normal/AY (which may heave a white patch on bib or head but if not there is no way of telling them from the pure normal) and 1 x AY so you're bang on average!

deffinately looks to be a Aust yellow baby to me good work

Hi Clarissa,
Definitely an Australian Yellow, congrats.
One of your photos shows the bird with a red headed hen, but you say the mother is an orange headed hen. If there are more than one pair of Gouldians in the aviary that it was bred in, then you have no certainty of the parentage of the bird.
If this is the case then you need to isolate the parents for the next round of breeding and hope they produce another, this is the only way to guarantee that the suspected parents are both split for Australian Yellow.
Just some food for thought.

What Natambo says about averages is spot on. And the fact that the mum has a white chin spot indicates that she is split Aussie Yellow, so one or both of her parents must also be split Aussie Yellow.
LML

so one or both of her parents must also be split Aussie Yellow.

If the offspring is a coloured bird and neither of the parents were coloured, then BOTH parents must be split.

I have normal looking birds producing the cream coloured chick but they are cream all over no green feathers what so ever on their backs
Would they be split to European Yellows?

E, bird **cannot** be split to Euro yellow, it either is or it isn't as it's co-dominant over normal. A hen cannot be green, a cock may be be green with with charcoal / blue bib and ring if it is single factor. It can't look like a normal.

Are the birds WB? because WB will remove more of the green from the back than PB. If not you're "lucky" that you have got a good strain of Aus Yellow (on the assumption you even wanted them to be splits and not pure normals).

To repeat
In one of my aviaries I have 4 Gouldians all are green backed,purple chested.The first clutch this season produced 4 chicks.
One chick was slightly darker feathered than what I refer to as normal uncoloured birds. Two were normal birds as I refer to.
The fourth chick is completely cream,no green patches on the back just even cream coloured.
Now unless it is a spontaineous mutation surely the parents are split to something.If not please explain?
This is the reason I am getting out of mutations and going back to pure normals.

is it possible to get a pic?

Yes, the parents are split to "something", but it's not Euro yellow. Most likely AY. Unless of course you do indeed have a new spontaneous mutation which would be reason for the rest of us to **choose** to stay in mutations .

As Misso said
