d'Uccle color genetics

Pics
I just got this little pullet yesterday. The farmer that sold her to us said she came as a free egg in an order of his from last spring. He said he doesn’t know what breed she is.

Based on reading online & her feathered feet, beard & muffs & teeny size, I think she’s a Belgium D’uccle... and a silver birchen color... but I’ve not found a Birchen d’uccle anywhere online.
Thoughts? What do we have here? Thank you!
She’s likely either a d’uccle mix or a mixed color d’uccle.

Thanks! I tried googling to figure out if all d’uccle traits (muff, beard, vulture hocks, feathered feet) would be dominant traits if she was a mix like with a Gray Japanese Bantam or something else birch colored, but I couldn’t figure it out. So those are all dominant traits then? She weighs exactly 19.7oz as a d’uccle pullet should. Here’s a photo from today after her bath & blow dry.

I’m not sure about vulture hocks, but feathered feet and beards are both dominant traits. Her coloration could result from multiple crossings, not just birchen x something else.
 
Dose anyone know if this pairing causes lethal genes

Brown Red Japanese x Millie Fleur = this…. My project D’UCCLES Brown Red Mottled D’Uccles

So I was wondering if breeding these 3 caused a lethal gene. I ask this because I put around 8 eggs in the incubator, 2 died as a small feathered embryo which is can happen some times, but I’ve had 3 fully developed, internally pipe and die. So far 2 have hatched and 3 are do to hatch but don’t look great. Is this caused be the lethal Japanese gene or something else?

Cute project!

I can’t answer your question, but thought I’d share this site on d’uccle genetics,
http://www.edelras.nl/belgians/genetics.htm#breedcombo

I’d also suggest posting on a Japanese thread (if you haven’t yet).

My thinking is that I’d choose a long legged Japanese rooster without the creeper gene, if possible. But even if the sire is carrying the gene, you should still get some percentage that would be able to hatch. Good luck!

All those letters confuse me as well. My history is with parrots, so I get which genes are recessive, which are sex linked, etc.... But I have NO CLUE when it comes to alleles, loci, and so forth. I just know "what to what equals what". And the fact that parrot sex linked genes involve the male and not the female (as in chickens) really threw me for a loop!

If you think of it as "colors" and "patterns" this genetic thing becomes a bit easier if you don't understand all the letters.

Mille Fleur is a pattern, and the pattern is pied/mottled.

Lavender is not quite a color - its a color DILUTER. It doesn't add color, it takes it away.

Add the lavender gene to the mille fleur pattern, and you have porcelain. The gold background color in mille fleur dilutes to become straw colored, and the black dilutes to become lavender colored.

Lavender doesn't affect white. White is not technically a color either - its a color "blocker" or "cover upper". Where there is blocked color or covered up color, it cannot be visually diluted.

Now, in the parrot world, we have "visuals" and "splits". Visuals are just that - they are "visual" for that color, meaning you can SEE it. Splits CARRY a color, and you cannot see it.

As for the mode of inheritance, lavender and pied/mottled are both "recessive" genes. Recessive genes must come from BOTH parents to become visual in the chicks. If it only comes from one parent, the chicks will inherit one copy from the visual parent and will be a carrier (aka be "split to" it). And recessive genes have nothing to do with the sexes of the parents.

So, if you breed a visual mille fleur to a visual mille fleur, one pied/mottled gene comes from mom, one comes from dad, and the chicks inherit both of them and will be visual mille fleur. Same thing with lavender - lavender x lavender = lavender.

But lavender (color diluter) and mille fleur (pattern) are two separate entities. One does not equal the other and they are totally unrelated.

So it stands to reason that when one parent is a mille fleur and one parent is a lavender, the chicks will inherit one lavender gene from the lavender parent, and one pied/mottled gene from the mille fleur parent. They need two copies of EACH of these genes to be visual. And since they only inherited one copy of each, they will be carriers of each (aka "split to" each) - and without TWO copies of EACH of those genes, their color will revert to black. SO.... Mille fleur x lavender = black split to pied/mottled AND lavender.

On the other hand, if a mille fleur (pied/mottled pattern only) is bred to a porcelain (pied/mottled pattern AND dilute color) the chicks will inherit one pied/mottled gene from one parent, and the pied/mottled gene AND the dilute gene (lavender) from the other. So they will get TWO pied/mottled genes and ONE dilute or lavender gene - there by making them visual mille fleur split to lavender.

But since a porcelain is a visual lavender mille fleur (it has the visually diluted color AND the visually pied/mottled pattern), and a lavender only has the diluted color (and NOT the pattern), you cannot expect anything but lavenders if you breed them together. One parent contributes a lavender gene, and one parent contributes a lavender gene AND a pied/mottled gene, therefore the chicks will inherit TWO lavender genes (visual) and ONE pied/mottled gene (split). In other words, the chicks will be lavender split to pied/mottled.

If wegotchickens got a black chick from a lavender x porcelain breeding, then something is wrong. One of the parents is not a visual lavender or visual pied/mottled.

Jeeze, my head is spinning - hope y'all's aren't...
Very helpful!! Thank you tons!!!!!
 
I can’t seem to find a description or any pictures of an ideal “Golden Neck” d’uccle rooster. I have a few and really need to get rid of one or two, but I’m not sure which specimens would be best to keep!

Ideas, opinions?
Just based on color at the moment, I’d also have to evaluate beard, comb, shape, etc, etc, but just color-wise/pattern, who do you like best?
