How did this chick hatch from a colored egg?!

[Chickychick33]

Hi everyone!
I have a question, or mystery that needs to be solved. Or someone to just tell me how this happened.

A couple months back I gave my sister two fertile eggs for her very broody Silkie to hatch. I have ameracaunas that lay very pretty light colored green and blue eggs. She requested that since she has no colored egg layers. So here’s the mystery..I have one French cucko maran. The chick that hatched out of one of those colored eggs looks exactly like my cucko maran. So it has to be hers. I know for a fact she does not lay colored eggs, she lays dark brown. She was on strike for 8 months when I got her and is the only chicken that lays those dark eggs so I know they are hers. The rooster is a black Australorp.
So please how did this happen?!

Black Australorp and Cuckoo Marans baby chicks actually look pretty similar until they grow more. Are you sure the chicks you gave her didn't just look like the father which was the Black Australorp?

If what you gave her was true Ameracaunas hen mixed with Black Australorp rooster, she now has Easter Eggers.

What colors are your Ameraucanas? Certain color crosses may have resulted in a baby that looks similar to your Cuckoo Marans. Does the baby have feathered legs? A beard or muff?

They hatched out of light blue and green eggs. Which I’m assuming they are Easter eggers. I’m just more confused on how a maran hatched out of a colored egg that was not hers. My ameracaunas are dark brown, light brown and white with some darker spots.

Does one of your ameracaunas have barring?

They are dark brown, light brown, and white with some brown spots. And no the baby doesn’t have feather on legs. These are both the chicks that hatched from colored eggs

No none do

One of your ameracaunas does carry the barring gene. Those chicks are sex linked. Cockerel is barred. Pullet is not barred.
The black color is from their father and it covers their mothers patterns. But barring will show.
It's not from your marans.
