Could my duckling be a Swedish blue?

[Melb26]

I have a five week old duckling that I don’t know the sex or breed. Any ideas? Thanks

I would say a Blue Swedish. Give it a week or two, and you'll be able to voice sex, females will go peep, peep, QUACK/HONK. Males will just peep for a few weeks, then start to sounds raspy.
