I was thinking of asking the same question, but seeing it’s been in the cabinet, so long it’s looking like you might have a Recessive Grey Libby. That’s the thing with those Recessive genes they can remain hidden for ages…this means both birds must be carrying the gene…must be like the odds of winning the lottery.

Damn! So I have all the luck with the birds popping up but none with the lottery! LOL!

Looks like she'll be getting kept now I feel sorry for my fingers!!!!

That's awesome Libby. Yep definitely not from another cock. She wouldn't be able to store semen through producing a clutch. Yay a recessive!.

Recessives can be carried around for ages, because the only way they can be shown is by breeding with another animal that has that same recessive gene and that usually means breeding back to the first beastie that produced it so that the offspring will have two genes that are identical by descent.

it would be interesting to let them rest of course after the clutch and match them again, not that you would get a grey again but if it is a recessive gene you would have a 25% chance, and here is the luck with that both my kids have blue eyes and Tim and I don't LOL so anything is possible because that is a 25% chance too.

??????????? Maybe the EGG Fairy!!!! , She has come in during the night and moved the eggs around just to be a B****.!!

Don't forget that there is a good chance that any blue series chicks in the clutches will be split for grey too

Gray factor is a color-adding factor. If a budgie has a grey factor, the color grey is added to the budgie's original body color. The grey factor is very strong and overrides the underlying color. Normal yellow-based budgies with a grey factor will be a grey-green color. Normal white-based budgies with a grey factor will be a grey color.

 

Basic Genetics:

Grey factor - dominant

Normal - recessive

 

The above means that birds can not be split for grey they either have it or they don't since it is a dominant gene

That's the Dominant Grey Elly…this as said is a rare Recessive Grey, so it follows the same genetic path as Recessives…also any of the birds bred from this pair have the potential to carry the Recessive Grey gene not only Blue birds, but it's only about 25% I think & only can be detected by test breeding.

 

Don’t know your time zone Elly, probably up too late or too early & drifting. Regards...Norm.

CONGRATS Libby on your recessive grey :hap:

Oh yeah that is right we were talking recessive my mind wasn't with the post at that time...I just saw the post and responded thank you Norm :hap:

Haha egg fairy, no I don't think so LOL!

These birds have two fosters with them which Can't be mistaken as they're YF spangles...

The only grey bird I have breeding atm is a Grey DF spangle crest bred, which definatly isn't the dadd of this bird as there were only two fosters to these parents which can't be mistaken :hap:

 

I've kept three of the chicks form these parents so far, soon to be 4-5 I guess

So Hopefully I'll have more of the gene floating around in my aviary somewhere

Remember 2 yellowfaces spangles can produce whiteface normals.

66% of the "not grey" babies will be carrying grey. That is because half of the babies in total will be carrying recessive, 1 quarter will be homozygous recessive and the other quarter will not carry it whatsoever ie, they will be homozygous dominant.

Yeah, I know they can produce normal whitefaces, but the fact of being Yf and spangle means they definatly can't be the parents who they were fostered to

I just keep it simple when remebering who has what 50% split 25% nothing and 25% visual
