How long can partially incubated duck eggs survive without the mother sitting on them?

I'm not sure. I didn't see any wounds when I did a quick inspection. Honestly at that point I was more concerned about the eggs surviving.

I'm pretty sure it's been about 2-3 weeks.

Did you check her for lice and or mites?
Were you sure she was getting up and eating?

So you aren't sure what day the eggs are in/what day is hatch day?

I lost another duck! I just found it dead in the coop! One of my khaki Campbells. It's wierd the ducks neck feathers are wet. It isn't even dark out yet. Any clue what could have happened

I'm sorry

I don't know what could have happened, maybe others will have a better clue.
