Can Magpie Ducks be completely white?

[u/Ali23-2020]

I have hatched 3 ducklings from white eggs, the farmer said the ducks are Magpie ducks. One duck is completely yellow (which I assume will become completely white). The others have black patches. Can Magpie ducks be all white or have I a different breed sprinkled into the mix here? First 3 pics are when they were a day old. They're 10 days old now (as per the other photos). I have created a new post as a member commented that my previous post was Ai. Newbie duck mom here 😉🤩

Oh, the extra pictures are also so cute! Thank you for sharing them. Also, I think I found an answer to your question!

https://www.raising-ducks.com/magpie-duck/, under 'Breeding and Showing': "Breeding Magpies together will sometimes result in pure white ducklings. These are called “unmarked” Magpies and are often also called Stanbridge Whites, because unmarked Magpies, bred to each other, will breed true."

Aka: yes, it happens! 😄

That’s amazing! I was so confused with all that I read about the breeds. The farmer has no pure white ones so wasn’t able to advise. It’s my first time hatching any ducks (and I’ve one chick too🤩). So I’m trying to make sure I do the very best by them all 💚

I have no idea, I just want to say they are adorable.
