My peking duck is laying on brown &white eggs..?

I found her today laying in a nest she made for the first time. Under her was 14 eggs. 13 brown & 1white. Could they all be from her? We only have one other female duck , which is what looks like a khaki, Im not sure of her breed. I thought pekings only layed white eggs.

That is really odd. Both the Pekin ducks that I had and my KCs all have laid pure white eggs.
