How can I identify the sex of new ducklings? What age must they be in order to
tell for sure? These are domestic ducks, part mallard.
I do not believe you can easily tell the sex of ducklings at least until they develop
adult plumage. Male and female wild mallard juveniles, usually through early fall of
their first year, are virtually identical in appearance. I am not sure about a hybrid.
