d'Uccle color genetics

First off I'll say that I don't have splash mille fleur or goldnecks. BUT I know if you continually breed splash to splash, eventually you end up with white birds that might have some black random feathers on them. So it could be that it is a splash mille fleur that has just been bred to splash so many generations back that the 'blue' in the splash (visible) has been washed out of the color. But that's another 2 cents of mine

Splash to splash = 100% splash
Splash to black = 100% blue
Black to blue = 50% blue, 50% black
Blue to blue = 25% splash, 50% blue, 25% black

Sorry guys, I'm playing catch-up.

I don't know if this has been answered (probably, but I"ll give you my opinion), but the easiest way to see if it is white or splash is to breed it to a black (normal mille fleur). If it is splash you should get 100% blue mille fleur chicks

Okay, still reading, but I"ve got a porcelain roo that also has this problem. When I got him I was under the impression that he'd just been 'bullied' a lot by other roosters, but that's not the case now and he still has it. Any ideas what causes this? I'm still reading, so I might find it myself

Again, sorry if this has been answered, I'm still playing catch up

Black mille fleur to black mottled: First you need to know your andalusian blue genetics. Black to blue results in 50/50 black and blue chicks. Then you need to know your mottled genetics. mottled (mille fleur--mottled columbian?) to mottled = 100% mottled. I don't know what happens to the mille fleur color, someone else will have to answer that one. But first generation chicks you'll have 50% blue mottled and 50% black mottled. I'm sure they'd be split to something with the mille fleur coloring as well, but I haven't learned that one yet

If this is the same one as on page 16, turtlefeathers said he is a blue mille fleur (I agree), not a splash. The gold neck is probably a splash or light blue mille fleur, which would leave you getting either 50% blue and 50% splash (if she is splash), or getting 25% splash, 50% blue, and 25% black (if she is blue).

*I might be wrong*, but in your top pic, I see what I think is a blue mille fleur rooster, not a black mille fleur.

And in the bottom pic, I see what I think is a gold neck hen (probably a splash gold neck as indicated by the blue in her feathers) and a black mille fleur hen - I see no blue mille fleurs.

If the rooster in the top pic was bred with the hen on the left in the bottom pic - and if their genotypes are as I indicated above - you WOULD get splash mille fleur offspring from them (along with blue mille fleur). As I said, one cannot get a splash mille fleur from a blue mille fleur x black mille fleur breeding - its genetically impossible, because Andalusian blue cannot be "carried".

I know what you are saying and I don't dissagree, I know that one copy of blue should dilute black and two should be splash but here are some of the offspring from this pairing. He was a young cocleral of 6 months at the time of that picture.

The one on the left has absolutly no black or blue on her at all, only white and gold.

And a cockeral (he looks better now than in that picture).

and a picture of the Hen when she was a pullet of 6 months.

He is the cockeral from this post.

and the golden neck (splash) is from the same post.

they are th offspring of the roo that turtlefeathers thinks is blue not black.

The splash is now in with my lemon boy along with 2 other Blue Mille Fluer girls.
This should give Blue Lemon Mille Fluer chicks.

What are you trying to 'work on'? If you want more porcelains you can breed your roo to mille fleur hens then breed the chicks back to the roo. This will get you a theoretical 50% porcelain chicks and 50% mille fleur chicks from their eggs.

Quote:
If your mille fleur hens produce porcelain chicks, either your mille fleur roo is also split to lavender or your lavender rooster is split to mottled.

Another page with a lot of errors...

Rule 1: You can NEVER breed a black animal from a splash (anything) animal.

Rule 2: Breeding with a blue animal ALWAYS gives you 50% Blue, not 25%.
The only way to get more % blue is to breed Splash * Black.
