I am familiar with ducks but can not I'd the light ones with the eye stripes. Bought them at TSC in a tub labeled swedish ducks. The black ones obviously look like black swedes but the light ones have me stumped. They are a bluish tan...eye stripes...sun spots like a baby mallard or rouen just a lot lighter... the pics make them look darker than they really are. Instead of beaks and feet being black...the are brownish ..the feet flecked with yellow. At three weeks old they are the about the same size as the swedes, so that rules out mallards. My tractor supply gets its ducks from mt healthy hatchery in ohio, so I am assuming they have to be a pure breed. So any experts out there with a good opinion on what these may be?
