Sorry for the bad photo but this is what they looked like shortly after hatching. The drakes are blue pied and silver pied and the hen is lilac/blue fawn. So mostly should be blue pied ducklings except for the three lighter colored ones, not sure on those.
The bigger blue duckling is one month older and looked like the solid dark headed duckling to the left.
This was them today minus three of the blue pied ducklings. I am growing out the three light colored ones to see what they will be.
