Gray Duck Eggs

I am going to regret this being my first post, but I should start somewhere right?

Two days ago, during my daily run I saw a Canada gray duck sitting next to the paved trail. This on its own is not that strange, most of the time these gray ducks hiss at you, but otherwise remain in place. What I did notice was what looked like hundreds of tiny soft feathers surrounding it.

I took note of it, but try to not bother the animals I see.

Yesterday I was walking to a restaurant with my partner and the gray duck had moved from its place and my suspicion was confirmed.

There were 4 eggs.

I have seen hundreds of gray (yellow?) ducklings, but never an egg.
