What's the genetic Phenotype is this chick's down color pattern?

[NatJ]

I posted pictures of the hen's Father, & Mother if you haven't seen them.

Yes, I saw them. But I don't have any other useful thoughts about the parents or the chick you initially asked about. My genetics knowledge is rather patchy--I know some things but not others.

Why not?

I have to employ test matings of that bird with others of known genotypes where the phenotypes of the resultant offspring would be looked. Some of those offspring might need to be test mated further to see what segregates out.

Okay. Since it's a cockerel, should I breed back to his mother?

To be honest, I have too many of my own issues to address. There are parties far more well versed in chicken genetics than I. My knowledge of genetics is limited to some of what I have personally, which is only a fraction of what is out there and does not include many of the alleles you are working with. Even with my birds, I cannot predict adult coloration based on chick down without knowing the genetic background of birds involved. I had learn through baby steps and genetics where not of the greatest interest, which is especially true now.

Any ideas: @Pyxis, @ColtHandorf, @The Moonshiner

Just saw this tag and I'm afraid I wouldn't be any help.

Okay, I'm back with a 6 week update.
It turns out, she does have partridge influence.
She has a very gorgeous topaz coloration.

So, she's e^b/E^Wh, Co/Co, Mh/Mh, Di/Di

Her legs are green, which is slate on top of yellow.

Cool! Is it for sure a girl?

My guess was pretty close- typical buff x black but with more buff leakage.

Her siblings.
The Wheaten it's a pullet.
View attachment 2268993View attachment 2268995Originally sexed as a pullet, then a cockerel. Was correct the first time.

Pretty nice buff columbian (or black tailed buff?)

 

[MysteryChicken]

You’ve referred to buff as wheaten because it’s based on it, so wouldn’t “buff wheaten” actually be “wheaten wheaten”?

Wheaten is usually light colored body, & red neck, & black tail correct?

So if you add Mh/Mh, Di/Di to E^Wh/E^Wh
It makes Buff Wheaten.

Regular Wheaten is either just gold, or red based without diluters.

Gold Wheaten + Di/Di makes just a lemon/cream Wheaten.

I don't have Screenshot shot, so I can't share the calculator results.

 

[MysteryChicken]

This girl is the only one really, who actually looks like she has partridge genes.

It's very poor quality patterning, like my Blue, Buff Partridge EE pullet.

 

[MysteryChicken]

One sibling is Wheaten, & the other looks just like her parents did.

So the other 2 I don't need help with.

 

[MysteryChicken]

Is it e^b/e^b, Co/Co?
E^R/E^R, Co/Co?
E/E^Wh, Co/Co?
If it's non of these, explain your answer, & share what you think it maybe?

The other chicks.

Yellow chick with line on head: E^Wh/E^Wh, Co/Co, or possibly just E^Wh/E^Wh.
Db maybe an influence, but not sure.

Chick with redish face: E^Wh/E^Wh, Mh/Mh, B/-
