What breed & sex duck is this?

[nemisis]

When I purchased these ducks they said they are rouens, I could tell that at least 1 was not a purebred ( I wanted purebreds), but they were in such dirty, filthy, dark, only a chick waterer to drink & not place to swim I could not leave any behind. Here are the pictures, the light colored one is not a purebred rouen, maybe mixed or a different breed? Has a ring around the neck like a drake, but a darker colored bill like a hen, drake or hen? They are around 51/2 to 6 months old. Please help me sex this duck.

I don't know if Rouens have a light phase. Maybe a mutation? Looks like a rouen just light. I can't tell if it has a drake curl or not in the pics. At this age, it should have a curl if it is male. Also, does it quack? Nice looking ducks.

The lighter colored bird is definitely a female. Females will occasionally have partial neck rings. She is a cross of some sort. Looks to be part Rouen though. In the 3rd picture down with the group of 4 ducks you definitely have two males and two females there.

2 drakes
2 ducks

Lighter one is either a light mutation phase Rouen duck or a Rouen cross duck

Thanks for the help, I was hoping for a female hen!
