Stumped by black chick with 5 toes

Pictures of Houdan I had before and the 5 toes on the feet of my houdan:

I wasn't sure about that, but I think they do carry multiple spurs.

Yep. Multiple spurs, but not extra toes

Having multiple spurs is very different from having five toes

This is driving me nuts LOL

SHE is supposed to be one of these breeds: Americana, Cuckoo Marans, French Black Copper Marans, Midnight Majesty Marans, Prairie Bluebell Eggers, Olive Eggers, Sapphire Olive Eggers or Starlight Green Eggers.

I understand most of these "breeds" are mutts but I'm looking at the crosses on Hoover's website that make said "mutts" and none of them have 5 toes??
For instance:
**Prairie Bluebell Egger= Araucana x White Leghorns
**Starlight Green Egger= Prairie Bluebell Egger x with brown egg layer (does not specify, however none of the chicks pictured on their website are black like this)
**Olive Eggers= Americana x French Cuckoo Marans OR Legbar x Welsummer

In my first thread about all the chicks, someone mentioned she could be a Mystic Onyx (she's not supposed to be lol), however her legs/feet are not entirely black and her skin is not black either.

She does have light feathering on her legs.

What does everyone think?

I have a mystic onyx from Hoovers hatchery that has 5 toes! It’s because they are a silkie/meat bird cross. From personal experience, Hoovers hatchery always seems to throw other breeds in with others that aren’t the same. I wonder if they do it just to fill an order for the feed store. This has happened to me 3 times so far with them.

Polydactyly is a dominant trait in all chicken breeds. She looks like a copper marans with polydacty

Yes they are (in reference to Mystic Onyx) Here is the link. I have replied on their other thread and am extremely confident that this bird is a Mystic Onyx

I have a 5 toed Mystic Onyx and she’s jet black from comb to toe! One of the hallmarks of the breed is that their skin is all black

I have the same chicken and suspected her to be the Midnight Majesty Maran. Mine had no feathering on feet but does have 5 toes. MMM was the only one in the rare choice birds that it could be. However they could have had a mixup and sent a Mystic Onyx instead.

So not from a hatchery bin? Pretty sure there aren't any assortments that a Mystic isnt in that a Midnight is
