Puzzled with hatching duck eggs

[Kate15r]

I have a few questions..
We have 6 chicks and two young ducks now, but have never hatched eggs. Well unexpectedly we got 7 ducks eggs to incubate, the only issue is with being a newbie I don’t know exactly how old they are, to know when to start misting them & when to begin lockdown. I’ve researched and researched but still feel puzzled.

Thank you all in advance.

I guess what I’m asking in short is, how old do you think these eggs are? I’m so nervous of not knowing and messing up with the humidity/lock down etc

Those look pretty close to hatching. How did it go?

They hatched not even 48 hrs after! 6/7 made it! Thank you for asking!
