Mystery Green Layer

[JacinLarkwell]

I have a green layer, but am unsure who and am trying to narrow it down. I'm selling a rouen in a couple days and don't want to accidentally sell the only green layer I have so far (roughly half of my older batch is laying now).

So I guess I'm asking if anyone knows who is most likely to be laying a green egg (I can get a comparison of it next to the white normal eggs tomorrow morning)
Breeds that are old enough to be suspects:
Pekin (normal, not jumbo)
Khaki
Rouen
Blue Swedish

I have one Rouen that is seperared with two other ducks just to see if the egg comes from that pen tomorrow or Sunday. If it comes from somewhere else, I'll at least know that she isn't the layer and can sell her

You're the only duck people I know that have birds other than muscovy, and I know my scovies aren't the culprit

Okay. Looks like some digging has made it likely the Rouens. So my question now I guess is if this is something I can breed for? The male is a blue Swedish, and I'm unsure how the green for ducks works. Only that I saw that hatching from green doesn't guarantee a green layer.

I haven't had ducks in a few years, but remember seeing this chart:

So statistically I'd say the Rouen. Even the khaki campbell, is derived from runners, I see it has a low chance of laying a tinted egg.

Since I don't have these breeds I am no help.

My KC and Rouen both laid off white eggs, sorry. Didn't have any of the others.

I had one Rouen duck out of three lay green eggs.

My swedish can lay off white eggs but haven't had a green one

She's back at it, whoever she is. 2 eggs in two days
