Two Indian Runner Ducks - Male or Female??

[Mr Peepers Mom]

Hello Farm Friends, I have a question for you. We have 2 Indian Runner Ducks, I have seen them do the hanky panky in the duck pond, at least I thought that is what they were doing. This year the duck/ducks are laying 2 different color eggs. My husband thinks they are both females and one lays white eggs and the other blueish green. Now I am dumbstruck,thought we had a male and a female. Is it possible that the female lays 2 different color eggs?

They both look female to me, neither has the curly tail feathers of a drake. The eggs tint may be slightly darker or lighter but they will never be a different color so it looks like you have two lovely ladies.
