Help please. Identify my flocks eggs

[Rayn -Rain-]

My questions are...
What breed of ducks do I have and which one is which. And which eggs belong to which bird....
Why do I ask?
I was given a flock of random ducks. I know some of them but not all.
The eggs thing.. they all lay eggs together. Chickens and ducks. So. I collected them all. But I don't really know which eggs are which. My kid thought she would help and washed all the eggs ...
So can I post several pictures and get help identify them.
I can get different angles of different birds for eggs I need to sell some eggs because I can't eat as many eggs as I am getting and I don't want to waist them.

First pic, left to right: pekin (drake?), blue runner(duck), rouen (duck), khaki (drake), khaki?, ancona (duck).

Second-to-last picture: front black and white is probably magpie (duck?), back probably ancona (duck?). Khaki (duck), khaki (duck), muscovy (duck or juvenile), muscovy (duck?). Ducklings look khaki; may be mixed.

Chicken eggs feel rough on the outside and may be brown or brown-tinted. Most of your chickens look to be layers of brown eggs. Duck eggs feel very smooth and are more likely to be grey-tinted. Ducks will lay their eggs on the ground, higglety-pigglety unless they're collecting them for a nest, prior to 9:00. Chickens lay their eggs, preferably in secure nests, prior to 3:30.
