Cant say for sure without seeing you do it, but I suspect the problem is that you are doing it wrong.

Um, if you sex it as a boy, there is NO question that you have a boy if that's what pops out.

Metzer farms has a video on sexing ducklings.
There isn't a dot with runners that indicates one or the other.
