What gender are my Pekin ducklings?

[chickenluv]

Here's my scenario

I have a White Crested Pekin female duck, and a plain ol' White Pekin male. About 2 months ago I took 5 of their eggs and hatched them under my little banty black tailed Jap hen.

2 of the ducklings have a crest like the mom, and 3 do not. But! 3 of the ducklings (2 have crest, 1 doesn't) have loud obnoxious female quacks, while the other 2 (1 has crest, one doesn't) have the raspy boy quack.

Does it sound like I have 2 boys and 3 girls?

Is it possible to have a female crested duck and get male crested ducklings? I'm confused

I'm plannign on takign some pics later today I can include if that would help. Thank you!

Well you can useually tell by the quack. But until the drake feather come in you really cant tell. Looks like you have a nice creasted tho.
