Help! I have duck eggs but don't know what kind of ducks they are from. How can I tell how long to incubate them?

I know some eggs go from 28 to 35 days, but how do I know when to stop turning them and when to raise the humidity level for the certain types of ducks when I don't know what kind they are? Do I still put them in lock down on day 25 and then wait 10 extra days?????? Help!! This is the first time I am doing duck eggs.

At day 25 check for internal pips when you candle them. If they have internal pips do lockdown, if not keep checking every day until they do.

where did you get the eggs from?
And how large are the eggs?
Muscovy take 35 days, calls can sometimes hatch out on 26 days, and other breeds take 28 days.
Calls would be small, so I would assume 28 days, on day 25 they should have filled the egg. I would wait until shadowing or internal pips to put them into lockdown.

Put the eggs in the incubator for 25 days. After, just candle on day 25 and check for pipping. If no pips, continue incubating. I would probably estimate 28 days average for some duck breeds. Others vary from 25-35.
