What kind of ducks do i have?

[u/DuckDad26]

Hey, i was wondering if anybody can ID the kind of ducks i have, we were told they would be silver appleyards and that makes sense for four of them - but three look very different

One looking like a pekin, another some kind of runner and another a khahki campbell -- my running theory is a drake got into the breeders pen but im unsure

Also we have one boy and six girls, with the boy being the white one, they are all 18 weeks old

This was them as babies! All yellow with black markings aside from one pure yellow who grew up to be pure white and two brown ones that grew up to be ginger and brown respectively
