The "Ask Anything" to Nicalandia Thread

[n8ivetxn]

Thank you in advance, for any pointers! I also have chick pics for down comparisons, if needed... Some of them were what I call a broken chipmunk pattern, some were yellow, if that helps. I also have pics of the hens that laid these eggs, if that would help.

What is the difference between these partridges? Why are they two different colors? They have the same parents. Recessive white Silkie x paint Nn

Are there two types of mottling? I have chicks hatch out like this or all white

They turn out like this

Then I have chicks that look like this

And turn out like this

@Egg Snatcher If it helps, Nicalandia made a post on the allelic mutations of mottling a while back. Like- years ago. Some of the photos have since become unviewable.

Someone else can probably explain it better, but just for sake of spitballing, I would guess you have 2 types of mottling hanging around? The thread Nicalandia started seemed to suggest D'uccle mottling was dominant over Japanese bantam mottling... I recall you started out your project with a brown red Japanese bantam x millie fleur D'uccle cross, which gave you mottled birds(not really possible unless the brown red Japanese carried mottling), so maybe that brown red rooster carried the japanese bantam type of mottling, and it's just been hiding in your line since, hidden by the D'uccle type?

I am not confident in what I'm saying.

Thanks, I thought I had two types. I am pretty sure my Japanese roo is carrier of the mottled gene. Thank you

@nicalandia or @NatJ

What pattern would this be? Or the likely genetics? Any guesses? I think my chick that I thought was a Brahma is part Silkie/satin as its feathers are coming in more similar to hers and the comb is looking dark and more walnut shaped. Baby is mainly white with a similar lacing mealiness in brown at the feather tips with pink legs and toes. Roosters are Buff Brahma bantam and recessive white d’Anver I also had a splash Silkie but she was taken by a predator sadly :-( I just don’t know when.

Not nicalandia or NatJ, but I'm guessing the adult hen is an incompletely or poorly marked silver Columbian or Db bird. I can't say I'm confident in saying what her exact genotype would be, or whether she has any additional pattern genes. I just know sometimes poorly marked db restricted birds will have that look of black leaking through their backs.

Maybe she has pg, or if not, is based on eb. I think eb makes those super patterned backs.

Thank you! This is helpful Just curious how the baby will turn out and impatient

I managed to sneak it away from Duchess to get better pictures. The upper legs are slate…wondering if the feet will change as it gets older like my splash Ameraucanas do. Definitely not a light Brahma boy haha I think some head feathers are coming in as well…it’s interesting that so much of the mom is showing in this baby, because the rooster boy I’m assuming was the father has very strong genetics—this is another of his children that I “think” had a d’Uccle mom. Literally looks like a buff Brahmas till the face!

Hi Nicalandia,
If I cross a Light Sussex Rooster over a barred plymouth rock hen will the chicks be sex linked? Males will have a white spot on their heads females will be all black?
This is what I believe will happen, however, someone is questioning me on it and I don't have the deep knowledge to explain it other than the pullets don't inherit the barring gene like the males do? Or am I wrong?

Not Nicalandia, but yes, that will produce sex-linked chicks.

With sex-linked genes in poultry, males can have two alleles per locus because they have a zz sex chromosome, but females are limited to one allele because they have a zw sex chromosome, the 'w' not allowing for another allele on sex-linked locus basically. Females receive their w chromosome, basically a null gene on the barring locus, from their mothers, and receive their either B(barred) or b+(not barred) gene from their father.

A light sussex father would donate a b+ gene to his daughters and sons, but the sons would also receive a B gene from their mother, since they get their genes from both parents. Males receive the gene, and get a headspot; females do not receive the gene, and do not have headspots. This one would definitely work as well, since the black base of the plymouth rock dominates the silver columbia base of the light sussex, so the white headspot of the males should be easily visible.


Photos included in case I didn't explain it well.
