If you are talking about a Mallard, you really can't until after about 9 months or so. We had two baby Mallard ducks hatch and grow up outside our kitchen window. We just moved them to the park near by after mom stopped showing up and they both look like females. As we have read, this is the case until they are 9 to 12 months old. We continue to visit them and they have about 200 new Mallard Duck friends now. They see us walking down to the bank and swim over, there is no mistake about which ducks they are.
