Ducks on strike since last fall!

[dpnation]

I've kept ducks for 4 years. I have three females at the moment - one is turning 4 and the others are turning 2 later this spring. They have been solid egg layers until now. It's not like they have tapered off - they are doing absolutely NOTHING!

They seemed to have an early exit into the winter egg break, which I thought was a little odd but I didn't perseverate on it. But now it's almost the end of March and I'm still getting nothing! My chickens have been back online for well over a month now.

My almost 4 year old Rouen molts in the fall and calls it a season, it's like clockwork. I realize she's getting old and will have lower production but she went from a very steady egg layer to nothing.
The almost 2 year olds - a runner and Cayuga - I don't know what their excuse is. They are still young enough to be laying regularly and there have been zero eggs.

Not much has changed in terms of care - same coop, same flock, same feed, etc.

Would appreciate any thoughts or suggestions!

Have you searched everywhere they could possibly make a nest?

Ducks can lay randomly on the ground or they might bury them in what ever materials they find. Anything the eggs could be buried under?

They have been confined to their coop and enclosed outdoor run up until last week (the snow finally melted). I need to give the coop a deep cleaning but there aren't any signs of eggs in there (typically they will make a nest)
