Cayuga or mixed

[Cyprus]

Do you think the black and white female is a Cayuga? Maybe the Rouen is the mom of the ducklings even though she didn’t hatch them?

I don't the that female is a Cayuga. She looks like a Cayuga Ancona cross.

I was wondering. Initially I thought she was mixed, then I learned that Cayugas could turn white as they aged, but that doesn’t explain the white on the ducklings
