@nicalandia I clearly don’t know how to identify down colors, I honestly cannot tell e+/e+ and e+/e^b apart.
I have never seen a concentric pencilled duckwing. Unfortunately, if they are on the internet I am hard pressed to find one due to people probably not identifying it as such.
So would the males be duckwing (with more hackle markings?) and the females with pencilling + a salmon breast regardless of whether it’s gold or silver?
I wish I had unlimited time and money so I could test this for myself.
But I don’t, so I’d like to draw the theoretical phenotype.

The chick down on heterozygotes is never crisp nor continuous. Concentric pencilled on homozygous wildtype is impossible. On itself Pg has no effect on Wildtype. Pg and Melanotic forms a type of double lacing but Salmon breast is still visible. Many pet/Hatchery Barnevelder lines carry Wildtype and often you will see hens with Pg/Pg Ml/Ml e+/e+ with a clear Salmon breast

Ok
I’ll just take down the e+ post then.

I can make concentric Pencilled Gold Duckwing on the Chicken Genetics Calculator. Wouldn't necessarily say impossible.

You sure Barnevelders are Duckwing/Wildtype? Most pictures of chicks look like Partridge.

Couple Hatcheries.

Speaking about Lacing though, I've got a Gold Duckwing Single Laced Cockerel.

Him as a little chick.

I said some lines of hatchery Barnevelder. SOP Calls for eb/eb.

The chicken calculator is for reference only. Concentric Penciling is impossible on e+/e+

I read many.

Thought the calculator was supposed to show what will happen with certain genes being combined, & such? It's a good learning tool, & if something is not possible shouldn't be shown on it.

Cackle Hatchery Barnevelders have e+ in their lines, you can tell the hens, but not the roosters.

e+ hen

The Calculator is not Perfect by any stretch of the word.
