Rouen or Mallard?

Just got these kiddos from Atwoods and was feeling curious. Not expecting a definitive answer, but excited for the guessing game.

I’d say both Rouens Rouens often have a prominent double eye stripe.

Check the back toes. By law, domestic Mallards have to have one of their back toes clipped off. If yours have both toes they are not Mallards.
