nodule confusion??

[finchman101]

ok ive been having a lot of confusion lately with what my gouldian offspring will be. Ok so i have two clutches of babies from different parents but have both DF yellow fathers and SF mothers. i get that if they are all to be yellow offspring their inner nodules have to be yellow but between the two clutches the outer nodules for one clutch is blue and the other clutch is completely white. and thats where im confused. does it really matter what the outer nodles are as long as if the inner ones are yellow all offspring will be yellow?
heres some pics....
blue outer nodules....

white outer nodules....

The inner nodules will be yellow unless the bird is genetically blue, in which case they will be white.
So yellow inner nodules does not dictate yellow offspring.

Also, a SF yellow bird that is visually yellow with a white or lilac breast will have mouth markings that are nearly identical to a PB SF Yellow ("Dilute") so the only way you will know is by looking at the skin color of the wings when they are about 5 days old. If it stays pink, you know the bird will be visually yellow. If they turn dark, they will be visually Dilute.

The baby in the last two pictures is a Yellow chick, for sure.
At first glance it looks as if all chicks in the top picture will be yellows, too - what are the breast colors of the parents out of curiosity?

I just noticed you're in AU - are any of the parent birds split for Australian Yellow? I wonder if this impacts the outer nodule color..

I'm not sure but I think Yellow Australian have specifically white nodules...I think I've read that on http://www.erythrura.net ...

So, I think some of your youngs will be Australian Yellow or split AY...

I do have pairs of Australian yellows on eggs at the moment but it'll still be a while before they hatch and by then I'll already know the colour of the other babies. I'll post some pics of the AY babies when they hatch to see the difference.
All yellow parents have purple breast and I would have no idea if they were split AY or not.

The baby in the second pic could actually be an Australian yellow, I was just looking at pics from another forum I am member of and the inner nodule is yellow an outer is white. Hopefully I'm onto something good. If it is an AY it should be completely pure yellow in back as opposed to the normal mottled back.

Stange for sure. I just double checked. All my yellow (Euro) offspring had blue nodules. None hatched ever had white nodules.

I was looking through my pictures as well - the outer nodules all retain some degree of blue even in DF babies:

Four yellows, two silvers:



Same clutch, later:

Ok so the eyes are now opened on it and they're red?? Not sure if this is normal or not??

I know very(VERY) little about Gouldians but just did a Google search out of curiousity and found this:
(scroll down to dilutes)

http://www.finchstuff.com/GouldianFinch ... tions.aspx

Basically it states that dilute babies can have reddish eyes that darken with age.

(scroll down to Back Colors and read under Yellow)

and last one - this chick looks alot like your babies nodules

I'm very curious to hear what the experts say - this is one interesting little chickie!

It can either be sex linked yellow or Australian yellow as both parents are DF so I shouldn't expect dilute unless I have a recessive dilute which would be very rare.
I see what you mean about the last link you gave me with the albanistic but I think my baby's body isn't as pink as the one in the second pic on that site.

Hey nixity, just wondering if you have any pics of your yellows just as the feathers are about to come through. It would help alot, thanks.

[nixity]

You mean like the second photo up top, or like this:

Yellow nestling with pin feathers: http://www.gouldiansgalore.com/Photo_Al ... in_jpg.jpg

Sorry, don't have these uploaded to photobucket so I can only give you links :/

[finchman101]

Thanks, I was wondering because mine are only a few days before their feathers start popping through and was hoping to see the difference.

Definitely is starting to look AY to me as the beak colour of all my euro yellows is alot darker as well as the insides of their mouths as compared to the baby in the pic below. Not to mention the outer nodules.
