Not sure who's it is, I think rouens lay an off-white egg and runners lay a white or green egg. Congrats on getting the first duck egg also!

My fawn/white runner lays white eggs and my chocolate runner lays green eggs.

It could be either ducks. All my ducks lay white eggs except for my Cayuga who lays a green egg. I have a blue runner, fawn and white runner, white layer, welsh harlequin and a Cayuga.

It looks like it could be either - feel their hip bones - the duck with the wider pelvis just laid the eggs. It should be 3-4 fingers wide. You just feel near their bum, and you will feel two sharp points of bone. If they aren't laying, or its a male duck, they will be two fingers apart.
