I have two recessive pied females. Since the colour on their bellies, etc is blue but the rest of them is yellow I am guessing they are GF2 recessive pied opalines :) I would like to stop the yellow bleeding onto the body colours so much so that they are essentially a yellow face with a white and blue pied body colour. I have a lovely GF male that isn't strongly bleeding into the body colour and who is also violet. The pied females are cobalt blue. Is this a possibly suitable match for this outcome?

Yellowface 1 and yellowface 2 are essentially two different mutations.

If breeding with yf2 birds the outcome will be yf2 birds and like wise for yf1.

The only way to get one or the other gene is to breed with it. So i'm not sure exactly what you're asking???

Whether they will cross or what? breeding yf1 to yf2 will give you a percentage of both, but as far as i know they can only really be on or the other??

Hmm, well essentially the female is YF2 pied and the male is YF1 I guess since there is only marginal colour bleeding on the neck feathers. I want YF1 pied babies

okay, well I've one some reading and this is where I am at:

 

The two females I have that I want to breed from are

 

1: Goldenface type 2 cobalt recessive pied spangle

2: Goldenface type 2 cobalt recessive pied opaline

 

I had thought to breed one of them to my Goldenface type 1 cobalt/violet but since they are recessive I gather this would not really give me the results I am looking for. So maybe a better bet would be a pied male. I have a few regular pied(as in not yellow/golden face) but I'll have to look in the daylight to see which are males. Since goldenface is dominant would I be correct in assuming that I will get some sort of goldenface babies out of this pairing?

 

So can anyone tell me if there are any other varieties (eg. opaline) that I can breed to a recessive pied and still get pied babies or does it have to be a pied or split pied parent?

I'm sure that with the YF2 variety you could select your birds wisely enough to reduce the bleeding a certain amount, because some birds bleed more than others

That was my figuring SW. Essentially the two females are almost completely yellow bled through other than in a few spots where their blue markings are, around the vent and the rump mainly so I would need to pair them with a bird that will reduce the amount of yellow. My GF violet male would have been perfect for this as he has not much bleeding at all but as he is a normal marked and the hens ar recessive pieds I won't get any pied babies that way. So unless someone offers up a better suggestion I think the best bet will be to pair them with pied males. The males aren't GF but since I believe that is dominant it shouldn't matter whether they have this trait.

I’m not so sure on YF1’s as they are not common, maybe they are YF2 but differ in the amount of bleed, as Sailorwolf said a lot could be done with selection of your breeding stock, when you get young select the ones closest to what you want to achieve. Like you say they are both Dominant so if they are different Mutations it’s best I think to keep them separate, so would be good to mate each of them with a white faced Blue. If they are Recessive Pied it’s often better to mate them with an improved Normal that’s split for Recessive if you can get one, to improve their type [body etc] as Recessive to Recessive often gives you smaller birds.

I didn't see anything about Yellowface 2 being dominant over Yellowface 1. I would essential think you would need to breed a white face to a yellowface 1 or 2 yellowface 1 together, adding the 1 & 2 together isn't going to stop the 2 from bleeding into the blue because the 2 is dominant over the 1.

 

If you want recessive pieds you always need 2 recessive pieds genes or as normal said both birds or 1 splt to the gene to accomplish it works exactly like the blue gene as it is recessive. What norm said about 2 recessive pieds together creates a smaller bird is correct too as I have read that also so it really depends there too what you are looking for.

From above, this is what I believe they are:

 

The two females I have that I want to breed from are

 

1: Goldenface type 2 cobalt recessive pied spangle

2: Goldenface type 2 cobalt recessive pied opaline

 

As they are recessive and I don't have a male split for recessive pied that I know of I was going to mate with a non yellowface recessive pied male. My recessive pied males are nice big boofy boys (still pet type but boofy) so they would certainly make some nice babies. Would I get yellow face this way?

If you breed a single factor YF with a White Face you are going to get 50% YF

If you breed a double factor YF with a White Face you will get 100% YF

Are you for sure the white face is not a double factor YF1? when this becomes a double factor it turns the bird's face white making you believe they are a true white face.

 

One factor to consider is single factors & double factors YF2, I am not sure if that has much to do with how much the bleed it but it does affect how it bleeds into the body.

I am beginning to suspect that this is such a complex situation that it might simply warrant a test breed. I have two similiar females, the only difference being that one is opaline and one is spangle. I shall pair one with the original GF that I wanted to breed with and one with a pied and we shall see what we get!

I haven't read the entire thread yet, but just for a quick reference there is only YF1, YF2 and GF... no GF2 exists. The GF acts similiar to the YF2 in how it bleeds into the body. If you go to my mutations page on my signature link, you can see photo examples of the single and double factor of all three types which may help you.

 

As far as inheritance of a GF to a whiteface, if the GF is single factor you'd get 50% GF, 50% white face.... if the GF is double factor, you'd get 100% GF chicks. Don't forget that white faced blues can genetically be 2 different types... either a "true" whiteface or a double factor YF1. This may affect the outcomes of your chicks if it is actually a YF1 double factor because he will throw 100% YF1 single factor chicks into the mix.

I have been trawling your page alot Raven :wub: Is there a visual difference between single factor and double factor GF? Whenever I call them YF I get told they are too bright must be GF, but when I call them GF people tend to refer to them as YF :hap:

yes there is a visual difference... (works the same as the YF2) in showing how it bleeds based on SF or DF... post a photo and we can tell you what type it is :wub:

If it's the same as YF then most of my birds are df, the one I want to breed to the pied girl is sf.

 

Am I making the correct assumption about my pied girl? If she is yellow and blue pied coming from GF stock would she only be yellow due to the GF? She is much the same as chrysocome's Millie... I am figuring this as if she was a yellow based bird then the blue patches would be green so that suggests that she is a white based bird and the white areas have been coloured yellow due to a seperate process, I was figuring GF df

a yellow & blue pied would have yellow replacing the white pied areas with yellow on both GF and YF2 birds... so it would be considered a white-based budgie.

I have some birds MB, that sound similar to yours, I thought they were YF2 as I bred them from two YF2 birds a Grey hen & Violet cock. They have a lot of Yellow in the areas that should be White, but in the Blue areas [Cobalt] there doesn’t seem to be any bleed of the Yellow. Even though they are small birds I’m keeping them to breed from to get further birds similar but improved in type.

 

I consider them YF2 but for some reason the Yellow isn't bleeding through the Blue, even though it is through the rest of the body.
