Black chicken laying green egg

[Striperguy]

Im new here so I hope Im doing this right. I have a question about a hen that my mother owns. She is approx 7 months old. She is black all over. Legs,feathers,comb,gills or wattles but her feathers have a green sheen to them like an australorp. She just laid her second egg today.Both eggs are a beautiful dark green.We were told this hen was a black maran. Apparently not.Any ideas on what she might be?

Does she have any stand out feathering? Like a beard or crest? Sounds like you have a Marans cross resulting in an Olive Egger. That means the Marans in her lineage had to have been crossed with a blue layer like a Cream Legbar or Amauracana.

No beard or crest. She is very slick feathered.

Pics of birds and eggs please?
She could be any cross.
Where did she get the bird?

Does she have a little feather crest on her head.....like this Black Copper Marans x Crested Cream Legbar?

She is most likely a Easter egger chicken. They lay a Variety of colored eggs.

maran are not created, she is probably easter egger cross or some kind of cross breed, some times people cross Maran hens to blue egg layers and get cross called olive Eggers, yours is definitely a olive egger

I think you can cross a Cream Legbar or Ameraucana with just about any dark brown egg laying chicken and wind up with an Olive Egger. But I'm not 100% sure, we'll let the eggsperts chime in.

I’m not an expert on Chicken Genetics, but from what I understand egg color comes down to two things. #1 certain pigment I the actual shell #2 pigment that is sort of sprayed onto the shell.
White and Blue eggs are part of the pigment in the shell while Brown is “sprayed “ on after. When a blue layer is crossed with a brown layer the offspring has both traits. Meaning a blue egg is “coated” with brown. This gives the tint from light to Olive green. Dependent upon the shade of brown.
So we know for a fact, that a chicken laying Olive eggs must be a brownXblue cross. I’d contact the breeder and see what the mix up could be. OR just enjoy the beautiful Olive eggs. You can breed her back to either a brown or blue layer to create more depth of color in her offsprings eggs.

EEs can lay a shell that is brown all the way, I have one of these now. I also have black EEs, they are crosses from black australorps hen, and some from a French Black copper marons hen with an Ameraucana/EE rooster..
They are very shinny out in the sun giving off purple and green colors, just luvely!
Also you can breed them to white egg layers for lighter colored eggs, like blue and light blue,,,,
