Wyandotte or Cuckoo egg

[Medodge]

So we got our first egg today!!! We have 3 GLW that are 22 weeks old and 4 Cuckoos that are 20 weeks old. Which breed do you think?

Congrats!
Looks like a wyandotte, a cuckoo maran egg would be darker.

I am fascinated that it’s striped. I assume that’s just a young pullet thing.

Cuckoo what? Cuckoo Marans?
If so, it's GLW.

 

[Medodge]

Yes. Sorry Cuckoo Marans

My cuckoo maran lays a light egg like that because she’s hatchery quality.

I would watch their behaviors and feel in between the two bones under the cloaca. If 2 or 3 fingers easily fits in their that means they allayed (it can happen when they are just about to lay too)

Spray Booth glitch.

I'd bet it's the Marans. SLW lay pretty light colored eggs.

You'll probably have to catch them in the act.....
...or maybe exam time:

Thanks you everyone. I really appreciate the imput.

It's less believable that a light egg layer laid that than a breed known for deep, dark brown eggs?

Hatchery quality is something else completely. I wouldn't count a bird that laid cream eggs a Marans.
