Identify the egg

[Sean Briggs]

Hello everyone,
I'm seeking help identifying what bird may have layed this egg and why it looks the way it does. The egg is presumably chicken or duck as that is all the poultry we have, it has a white shell with green dots of color on the shell. The dots are part of the shell not something stuck to it or growing on it. The color of eggs our birds have produced in the past are white, light brown, pink / light brown, brown with speckles, dark brown, blue, white(duck), green(duck), and ashy white to black(duck).
The only new additions to the flock this year were some additional welsumers(brown with speckles) and an Isbar. I believe the isbar layed some green without speckles but can't be 100% sure.

The breeds we have are white leghorn(white), Easter egger(blue), gold laced Wyandotte(light brown), blue copper marans(dark brown), welsumer(brown with speckles), isbar(green?).

Any idea what this egg is from or what causes the coloration? The speckles are more green in person and the background color of the egg is more white.

Duck Egg.

Duck Egg.

Why do you say duck egg?

We have had the ducks for over 4 years and never seen one anything like this before.

Not saying it isn't possible but just wondering what your reasoning is.

I have a Peking Duck that lays white, with a light grayish, green coating. Occasionally spots.

Interesting, when that happens are the eggs nrmal other than having spots on the shell?

I'll let everyone know if it looks fertile when I candle all the eggs. If it is fertile then we'll know for sure it is a chicken egg as I have no drakes but in the mean time I will tentatively figure it is a duck egg. it's just weird because it is so different from all three of my ducks normal eggs. The one duck that lays white normally has a more waxy/luminescent appearance to the shell and the one that lays the green eggs has a very rough texture and is closer to goose egg sizes than chicken egg.

The eggs are perfectly normal. It's just odd distribution of bloom, & pigment.

Yes, be sure to update.
