Rural Gardening: Are We Pekins?, 1 by DrDoolotz

So, today we got 5 new ducks from the local animal shelter. Two appear to be domestic mallard females, I think. I have another duck I thought was a domestic mallard female but now I think she's a Rouen. Does anyone know the diffs between Rouens and domestic mallards?

Anyway, I thought the other 3 were Pekins, but they are much yellower/creamy coloured than my very white Pekins. Are there other similar breeds to Pekins that are white-but-yellowish?
