Need help identify some cross breed ducks

[isopuppy]

About 9 weeks old all have banded colored strips on wings that are the blue gree spectrum no black lines on any of the eyes and one has a white neck and wing tips . Another is very dark and was a little black duckling!! I bought them all together at a feed store. Help!!! New duck lover from the Pacific Northwest

Ducklings can be difficult if not impossible to identify just like small chicks. Post pictures as they grow, and someone can help you identify them. Good luck with them.
