Shows you what I know...

Regardless I do think she might have the Charcoal gene. Something to account for the black neck.

Dark Cornish chicks (wheaten)

What makes you say those chicks are Wheaten?

Black Belly, & neck. Both the chicks have the black belly.
It's a possibility. I don't remember Mocha(Dark Partridge with Charcoal) having that feature though.

Baby Mocha from the Black to White Experiment for Comparison.
This wasn't a great picture.

Dark Cornish are just known to be wheaten based. Maybe not all are though.

The ones on the APA site look like this though

McMurrays look like this? Duckwing?

The first ones were from Cackle. It almost looks like they were partridge, APA were whesten, McMurrays duckwing (except the two on the left). But is it possible all of these could be dark Cornish?

Somewhere a few years ago, I read that the Dark Cornish in Australia are Wheaten based, and there were photos of light wheaten-looking chicks. Unfortunately I can't remember where I found that.

But the chicks I've seen in the USA mostly had stripes that made me think e+

Here is a relatively recent thread with photos of Dark Cornish chicks:

I think that person does have mostly Wheaten in their Dark Cornish, based on what chick color they consider normal (light yellowish) and what they consider unusual (brown with stripes.)

I've had Dark Cornish chicks from several hatcheries, standard sized and bantam, that had stripey chicks but never the light colors I would expect with Wheaten. But one hen went on to produce some chicks that looked Wheaten and others that had stripes, so I guessed that she was probably split Wheaten and e+

For the chicks in the little video on McMurray's website, I would guess there is at least on Wheaten, several that might be e+/e+, and some that have an in-between appearance that might (maybe) come from being E^Wh/e+ (or something else yet, but I don't have any guesses on what else it might be.)

I still have trouble trying to tell some of the e-locus genes from chick color, but I have been tentatively considering that Dark Cornish can have either Wheaten or e+ or both, with one or another being more common in some breeding lines and even some countries.

If someone knows more, I'd be quite pleased to learn what is actually going on with them!

I am thinking you are right and they can be both.

What happened to the whole Partridge subject?

I guess Partridge, Duckwing, and Wheaten can have the same phenotype in certain patterns?
