BBS breeding and dilute / white splash

[MysteryChicken]

Breeding her to her own son would work equally well as a test for recessive white. It just takes longer (need to raise a son to adulthood, as compared with using her father who is already an adult.)

Yes, I can see why you would want to keep recessive white out of your flock of BBS.

If you want to be sure your BBS flock has no recessive white, you could test-mate every bird involved (breed each one to a recessive white, hatch enough chicks to either find a white one or be reasonably sure they will not produce any white ones.)

Oh, I just remembered, there is now a test for recessive white:
https://iqbirdtesting.com/whitegene
Testing one bird (the puzzling pullet) might be cheaper than test-mating, by the time you consider the feed & time involved.
They can test a sample of blood or feathers (or eggshell, but that would mean the shell she hatched from: I'm guessing you no longer have that.)

If she has recessive white (confirmed by test mating or a DNA test), I would be suspicious of any other chicks that originated in the same flock. If she does not have recessive white, there is no real reason to suspect any of the rest would have it either.


That does sound like it will give you quite a variety of chicks!

First time I'm hearing of this recessive white, gene DNA test. Hopefully they come out with other color mutation DNA tests as well.

They had lavender too on the list from the site referenced. I'm sure they will co tinge to add more options, pretty cool stuff!

Nice.
I hope so. I've got so many funky things that happen with my birds, it would come in handy.

Do you know if this would work for all recessive whites? I have phoenixes that have a recessive white, but I think it's a different type than other breeds

I haven't heard of there being any different forms of recessive white, but that doesn't prove anything-- it might exist without me hearing about it.

All I know about the test is what the page says. I suppose you could pick a bird that you already know about, get the test on that bird, and see what it says. That would tell whether their test identifies the recessive white in the bird you have.

I know that, outside of the c-locus recessive white, there's also one that is allelic to mottling, mo^w, that is referred to as tyrosinase-independent recessive white if you want to look more up about that. Not sure if there are any more or which Jacin is referring to, however.

That was a fun read! Thanks for that! I'll have to save it to read again when I have a bit more time to really digest it.

Very interesting. I don't remember reading about that before.

I really don't know whether your Phoenix are more likely to have that mutation, or the usual kind of recessive white (c locus). I suppose they could even have both

My phoenix have hackle leakage, which is what makes me think they have this. Every single recessive bird has had multiple brown and black feathers at one time, often consecutively, where other recessive whites are not supposed to be able to show any leakage from my understanding

 

[pipdzipdnreadytogo]

Tyrosinase-independent recessive white is prone to being a little 'leaky', but generally in stray pigmented feathers here and there. More similar to heterozygous dominant white letting stray black feathers 'leak' through than to dominant white in general letting gold pigment leak through, if that makes sense. C-locus recessive white birds can have a pigmented feather or two show through occasionally, but definitely not commonly, and often in juvenile feathering when it does occur, which is then shed out by maturity. At least, that's been my understanding of these genes and has been my experience with recessive white in my own birds.
