Which drake mix for these runners and pekins?

[JoJoM]

Picture number 3 looks like a Rouen duckling to me but there is another breed that mimics it so I could be wrong. They sure are all darling!!!!

I think that one is Rouen/pekin. Kids named it Viper lol.


This one cayuga/blue runner - Tyrone


Then yellows are 2 full pekin and one pekin/blue runner - Waddles, Eddie and Walter


This one Cayuga/Pekin - Webster


That leaves Stanley. He was definitely a Blue Runner egg. He’s still the big question. Small and so pretty.
