She looks lavender in that picture, but it's just the lighting.

Ha! I got it. This is the hen who is grey with white mottling and whole spotted feathers, the picture isn't great. I'll get better pictures tomorrow if you would like.

does the gray sort of match porcelain gray?? that could be a factor, if so now you have to add lavender to the equation! i would try to compare to mine but i have about 50 or so at different stages of development-none are more than 6 months old and i want to see what their final adult molt will produce. it is sometime hard to see the pattern on light birds, it can be helpful to remove a few select feathers and put them on a dark or white background and adjust contrast. check out this chart-apparently mottled is not just recessive.... apparently splits for mottled can show a few spots

It's a lot lighter than the porcelain color, it's just a little bit darker than white that it is noticeable. She's the only one that look like that though.
I have a few young birds, three are splash. Only one is showing splash markings the others are pure white. The color between the birds with markings, and the birds without markings is remarkably different.
The Golden Necks I've seen look different than my rooster that was produced from the Splashes, unless the roosters I saw were falsely labled, or I'm confused on what I read, either way.
Maybe that's why I see spotting on her, that's really interesting.
I have a few pictures of individual feathers from different birds to show the different markings, I'll post them soon.

These are feathers from the hen with mottling.

These are from one who is white with blue and black marking. Some of the feathers from these birds are odd in pattern, none look the same. In pictures the small splashing, especially the blue is hard to see. It doesn't help with my horrible photography skills.

The hen who's feathers are in the second picture. They've been gaining more markings with each molt.

Because the blue is harder to see, I think this feather shows the blue much better than the others.

how does that work out? wouldnt a lavender over a millie produce solid black? were there some genes hiding in them (not hatchery stock?) right now in my pattern pen i have blue millie, millie and GN hens covered by a porcelain, black mottled and a lavender roo - i was expecting to easily isolate the chicks from the lavender or the mottled at birth expecting them (as per chicken calculator) to be black or blue (whereas the offspring of the porcelain would be brownish). is this not going to be how it is?

oh and i DID find a site with photos of B/B/S duccles.....it's in Australia....
--the first one is even splash for the millie pattern!

lavender x Millie would be just like Millie x black. The offspring will carry 1 copy of lavender though. The calculator says black but the Columbian usually leaks and gives a brown red appearance. But my outcome had to be from my lavenders being made from porcelain. Still the Columbian background

wow those sound different than mine-especially the blue in the splash. it really sounds like your genetic wildcard has to be the splashes. according to a few other web pages the golden necks are 'aka'd splashes -which makes sense in the mottled/mille fleur spectrum, but once you have an actual splash (a real splash) then ??? photos would be nice, i want to compare them to mine. do you have any idea about the history/breeding to produce those splash hens? are they 'pure' duccles or bred back from introducing a colour?

Golden necks are Millie's with dominant white added( covers the black so the bird is buff with white spots) a gn with 1 copy of white can have leaky black feathers throughout its body. ( ex: paint silkies) a gn with 2 copies of white won't show any black. MF x gn with 1 copy of white = 50/50 mf- gn offspring. Mf x gn with 2 copies of white = 100% gn offspring.

Millie splash is a millie with 2 copies of dominant blue. ( 1 copy makes a blue millie) the 2 copies of blue make the black areas of a millie turn white with the dirty ticking as seen in all Andalusian blue splash birds. Mf x blue millie splash = 100% blue Millie's.

Gn and blue millie splash both can look identical. Close inspection of feathers can distinguish them sometimes but breeding to a millie will tell for sure.

Another close bird to the GN is a buff mottled. The difference in those is a buff mottled has a buff tail where a gn tail is white.

A project I've had.. Lemon blue.

 

[Matthew86]

My next project:

Porcelain x gn ( 2 copies of white) = 100% gn offspring with 1 copy of white carrying lavender.

Porcelain x F1 gn = porcelain, mf carrying lavender, gn carrying lavender and creme mottled ( gn with 2 copies of lavender- which will dilute the buff to creme as in porcelain )

I'm not great with the genetics, so I might have a simple question to answer, but I'm very puzzled. I would extremely appreciate it if someone could answer...but to get on with it, I bred Splash to Mille Fleur and got Mille Fleurs, Splash, and Golden Neck-which I was expecting. But four birds came out of the cross that I wasn't expecting, unfortunately my better looking of the two roosters died over the winter, but I have a trio left of what I thought were Mille Fleur that didn't develope their mottling yet. Well, it's been two years and there's not a drop of white on them. Am I missing something that is easily explained, or shouldn't this happpen? Or maybe they just need more time to get their spots? I'm rather confused, and I thank anyone who can help me out.

Mottling is recessive ( takes 2 copies to show) so to get millie offspring both parents have to have at least 1 copy of mottling each and Columbian background. The odd ones you hatched probably just have 1 copy ( sometimes shown in black ticking on the feathers) as far as getting a splash, both parents have to have 1 copy of blue which the birds listed, a millie doesn't. So your " splash " parent is most likely dominant white x millie cross. ( will make a white bird with ticking like a splash with 1 copy of mottling) and that x mf will give your offspring listed.

I'm sorry, I hadn't realized that you answered till now. I also have a new piece of information, the birds are supposed to be carrying a silver or gold gene. I'm not sure if that changes anything. Thanks for the reply, and sorry for my late one.
