We were given this abandoned duck back in October. It was found walking along a busy highway. Initially I thought it was a blue Swedish duck because of the coloring. But some of its characteristics don't seem typical of the breed, from what I've researched. It's likely a "mutt duck" but what other breeds would you guess it is? The last picture is from October, when we got it. The ringed eyes, and the ridged bill, don't seem typical of Swedish?
