I have been slammed with requests for YF (YF1 or YF2) birds. I have bred one pair that has produced them (only 3 out of 10 babies). I have to give this pair a break (they had two clutches in the past few months) but the demand for the YF birds they throw is high. I need to give them a break and want to pair up another set of birds to continue my chances of getting YF chicks. My question is this... if I pair any YF male with any YF female do I have a better chance of getting MORE YF offspring or are the chances just the same if only one of the parents were YF? Do I need to be selective in my pairs? Will certain mutations over run the YF mutation resulting in NO YF babies? Some adive woudl be helpful.

are your birds yf1 or 2?

 

Id assume pairing 2 yf2 birds together you would get all YF2 chicks. Only having one parent bird as a YF reduces the % to 50%. This could come out in a clutch as 1/10 or 10/10 depending how the genes throw at the time

Doesnt YF to YF produce DF YF ? making white faced chicks ??

That's right Kaz, I have never done it but that' what I have been told.

If you put 2 yellow faces together you will get DF yellow face birds which have a white face but those DF white face yellow face will through yellow face to all there young.

not in yf2. so I was told

are your birds yf1 or 2?

These are the only YF birds I have...

 

Still not sure if he is YF2 or Goldenface.. but this is the one that needs to take a break

 

This one I think is a YF2 Dom Pied Cock? He is already paired with a hen and they have 6 eggs (2 hatched, 4 to go)

 

This one is too young... but I think it's YF1 Greywing Cock?

 

This one I'm told should be 12-18 months by mid summer... but I think it's Opaline YF2 Hen?

 

And this is just a new bub (2 months old) Creamino Hen (Goldenface Albino)?

YF type 1 to YF type 1 will give you double factor YF type 1 babies that appear white faced but will only produce yf babies (when paired to a blue line bird)

 

type2 will still show as yellowface double factor or not - although the double factor bird can appear more patchy in the colouring on the body.

 

 

 

what is your pied paired to??

Pied is paired to a Dilute Dominant Pied Greywing Sky Blue Hen... ??

If you pair 2 type 2 yellow face birds together you will get 50% single factor type 2 yellow face, 25% double factor type 2 yellow face and 25% normal white face. So that is a total of 75% with yellow faces. If you breed from one of the double factors they will produce 100% yellow face mated to any blue based budgie

 

If you pair 2 type 1 yellow face birds together you will get 50% type 1 yellow face, 25% normal white face and 25% white faced birds that are double factor type 1 yellow face. Visually the double factors will appear the same as the normal white faces but if they are bred to any blue based bird they will produce 100% type 1 yellow face

Your hen appears to have no iris rings

Your hen appears to have no iris rings :rofl:

 

 

We went through this before KAZ... Remember...? I was going to breed 8 pair and it was suggested (on here) that two pair inparticular not be bred because they looked too young although they are 12 months old... well I followed that advice, I didn't breed the pairs that everyone was concerned about, and only bred 4 pair and this was one of them.

 

She and her mate are wonderful parents. She produced 7 eggs, 4 babies have hatched (3 more eggs to go) and they are all doing fine. She even fostered one chick for a few days for me.

This is this hens iris ring picture that I posted before.

 

 

That being said... back to the topic... it was asked who I paired this YF cock with... so is there more to add now knowing the hen??

So shes definitely dom pied then :rofl: Pretty when greywing is involved in dom pied I think.

Agree with nev. And it depends who you talk to, but the YF thing is a bit silly and they should really be called "par blue". Dont think this is the time to get into that arguement lol. I could go into the genetics as far as i have learned them, but basically nev is right. YF2 x YF2 will get you normals, yellowfaces and double factor yellow faces. You can tell they are double factor because the yellow tends to be brighter, and instead of bleeding throughout the whole body it is in the mask, wings and upper chest - leaving the belly and rump blue. These will produce 100% SF yellowface 2's when paired to normal blues. I will be breeding some double factor YF2's next breeding season (around september).

I asked becuase you said he was already paired up, with her as the partner you have a chance of getting some yellowfaces out of the clutch, either normal or dom pied

Edited March 3, 200916 yr by *Nerwen*

if she pairs them she will get all dom pies 50 percent the cock is split rec so she could get black eye yellow or blues (white bird)sorry im old school terms lol and your odd rececive pie

as for the yf thing i breed yf by the dozzen

if you want all yf then get a sky or cobalt harliquin..par blue .. yf2 sky blue rec pied what ever you want to call it and pair it with a sky violet spangle hen and you will get all yf2 and mabe one or two white face chicks

then pair a normal cobalt par blue cock from this pairing to a yf 2 bird and you will get all yellow face two chicks

i could go on to say that if you pair a yf2 df sky or cobalt dom , with a cobalt yf2 norm /cin /opaline you will get all yf2 birds and all hens will be cin and opaline and make beautiful chicks and adult birds the pair you have their will give a simular rezult with beautiful chicks i dont know about the genetics side but you will get 50 50 yf and white face

but i no expert this info all from hands on but out of many chicks i always get 50 50 yellow face or sometimes more with this pairing i stated i always pair my yf2 sky and cobalt,violet pied cocks, with normal cobalt parblues from spangle cin opaline hens to sky violet spangle hens either opaline or cin or both chicks always beautiful with many veriations of colours and mutations

So for the purpose of selling to individuals for "pets" that want the appearance of the yellowface, it's best to just pair one yellowface with another non-yellowface bird to get visual yellowface chicks? And in doing that I have 50% chance or less of yellowface chicks with this kind of pairing? Right?

You only have to worry about pairing a yf to a normal blue if you are working with the yellowface type 1 gene.

 

to get the max chance of chicks with the yellowface gene you can pair two together if using the yellowface type2 gene. As Neville states that is a 75% with yellow faces (of cuase in clutches it can vary this is a % of and average)

I'm mainly working with YF2 birds. And my goal is to get visual YF1 or YF2 birds, not just have them carry the gene... the people asking for them like the look of them as pets, not wanting to breed and get more YFs in the future. So to achieve the most VISUAL YF chicks, as long as I have one VISUAL YF parent I have at least 25% chance of getting YF chicks from the pair if they are paired to any other blue series bird, RIGHT??? (I hope I'm inderstanding this??)

50% chance.

 

and Yellowface is a dominant gene and so can not be carried in a bird

If you breed 2 YF birds together (planning not to sell the white faced chicks as they will most likely be DF YF)

, you'll get a DF YF for future breeding then you will get 100% YF's in a years time when you breed from them...

Edited March 5, 200916 yr by **Liv**

But Liv Chrissy is useing the type 2 yellowface gene which doesn't give DF YF appearing as white facesa

Oh i see. learn something new everyday
