You can get ducks from this line that range in color - from a light cream, a slate blue, to black. All ducks will have a magpie or tuxedo look - white wingtips with a white chest. 

These ducks are a mediumweight breed, suitable for meat production if you see fit. 

They lay a light cream/white egg that is large. 

Flying ability is poor, and they wont fly away. 
 
This is a mallard derived duck.
