Identifying duck breed

[Magsaroo]

Hello, I’m not new to raising ducks, but recently bought 3 more listed as Pekings. I’ve noticed one doesn’t look like the other two or my others when they were babies, and was curious if anyone could help me tell if it’s a different breed? None of my other Pekings have had the dark coloration on the head, and back. Thanks in advance!

It sure is a cutie! does this duckling stand up tall or squatty like most domestic ducks. Just wondering if its a Indian Runner

i agree with miss lydia it does look like it might be a fawn and white Indian runner. if it is, it would be smaller than the two Pekins and stand taller
