Checked in the aviary today and....

Opened up the one mandarin box and found a white duckling and a few eggs pipping! Very excited this pair produced at least one white offspring....the pairing is a White Drake over what I thought was a regular coloration hen but someone must have some white in her background

I think your hen is still normal genetics. A white male over a normal hen can throw white female offspring

Thanks for the post Kansas! She will be sticking around here then as I know I have a split drake in need of a new mate.
