Gouldians - Blue hen + split for blue yellow cock = ?

What outcomes can result from a blue hen with a split for blue yellow cock? In the nest a couple are greenbacks, one is silver and one is what looks like a blue (dark grey back atm)

What will the greenbacks be? They'll actually end up with green body colour?

barring any hidden genes your males will be Single Factor YellowBlue ("pastel") and/or Single Factor Yellow ("dilute") split to Blue. Your hens will be either YellowBlue ("silver") or Yellow split to Blue.

I would say the dark grey back one is the "pastel"and the greenback ones are will be the "dilute"

Good luck

I was told the yellow cock had a yellow cock as his dad and mother was a silver split blue. Does that make any difference?

That would make your male a Yb/Bb

What kind of young will I get if I put one of these silver hens that comes from this pair together with a blue male, or is that a bad idea?

Also what if one of these silvers was put with one of the yellow body/split for blue males, what are the results?

What you would get:

Pastel Males and Blue Hens

Would I recommend it? Not personally.. others have varying ideas on this.

Edit:

Yellow/Blue Male x Silver hen (If the male is DF) would give you DF Yellow/Blue Males, Yellow/Blue Hens, Silver males and Silver hens.

If the male is SF Yellow you would get Dilute/Blue Males, DF Yellow/Blue Males, Normal/Blue Hens, Yellow/Blue Hens, Pastel Blue Males, Blue Hens, Silver Males, Silver Hens.

Edit Again:
You're not intending to pair the siblings together, right?

No, just looking at options atm. I have 3 pairs of unrelated mutation gouldians, a yellow cock split for blue with a blue hen. A blue cock with a normal split for blue hen. A blue cock and a blue hen. Funnily enough the only babies to survive from the first lot was from the pure blue pair, the male is a good one though, big strong bird, better than most normals even.

Also I asked about putting a silver hen with a blue male, but you didn't answer it. Even a silver hen with a normal greenback split for blue male.

Finchbob,
Here is a free gouldian genetic forcastor on line. Just click the colors of the cock and then the color of the hens and it will calculate all the possible offspring mutations possible and the percentage that they may occur. Have fun checking out all possibilities :D

There's a really good free gouldian forecast program by Carlos Matos - you just have to email him for the serial number

Debbie,
I have got the code from Carlos but still can not get it to download. I don't know what I am doing wrong.... maybe some of my computer virus protection software blocks it??? Not sure but I have tried many times... so I use the other one with no problems.

But there you go finchbob, now you too can be a genetic whiz :D

Sorry to hear that Candace. Have you tried emailing Carlos? He's really good at responding to any questions.

Yeah I did - it was the first part of my answer before I saw you asked about another combination:

This pair would produce Dilute/Blue Males, Pastel Blue Males, Normal/Blue Hens and Blue Hens.

Back to my yellow/split blue cock + blue hen, the genetics calculator has caused some confusion with what debbie said.

According to the calculator, if the yellow cock is single factor or double factor makes a big difference on the colours of the offspring. How can I tell if the cock is single factor or double factor?

So far the offspring that came from him, out of 5 of them, 2 appear to be silver, 2 have a green colour back, and one has a dark grey back. Does this help in learning if he is double or single factor? From what I can see, a DF yellow cock would have not resulted in any green coloured chicks as it's not possible.

A SF yellow cock would result in both green normal split for blues or dilutes, which means the greenbacks in my nest could be either?
