Well done okiebirds on your breeding results I my self have been breeding blues for over 25 years and out doors
but protected from the cold I have breed over 100 birds this year and on the opinion of some people they are not week
but strong you just have to out cross every year.
cheers cf

I bred blue/silver back to green/yellow common stock.



Okiebirds,can you explain how you can have green birds split for yellow and blue birds split for silver. Cheers Craig

I dont Craig.... sorry its just bad punctuation thing on my part. Yes the / (forward slash) is used to signify a "split" I merely used it as "or". Meaning blue/silver = blue or silver green/yellow = green or yellow. I can see how it could be confusing. Its just a bad writing habit.

A pastel blue cock is split for blue,silver, green, yellow, depending what it is paired to can produce all four results

That's not correct, a pastel blue cock is a blue euro yellow of which the yellow dominates the darker colours of the blue making it pastel blue SF or Silver DF cock.It is not a split,it is a combination of two colours. Craig

Ps thanks okiebirds for for clarifying that,i was just wondering how you could have split EYGB's. Cheers Craig

Well said Craig 52 you still know all you're Gouldian mutations

Cheers Flav,Welcome back. Craig

Pastel blue cock (SF) carries genes for yellow and green, when paired to a split can produce green, yellow, blue and silver young, so Craig what is incorrect about that.

I am aware pastel DF is a silver caring the yellow gene only, but the pastel (SF) (cock) carries the green and the yellow gene, when put into breeding program paired to a split green back hen produces 8 outcomes of 12.5% each, offspring being green, yellow, dilute, pastel, blue and silver off spring

Correct,the green off spring are split blue,the yellow off spring are split blue as is the single factor hens (don't use the word dilute)you should not produce SF cocks as EY is sex linked dominant so pastel is SFYB blue cock which should not happen.
Blue will happen as will SFYB blue hens called silvers if that makes sense from that pairing of SF pastel blue cock and a split blue green back hen. Cheers Craig
