If they are pipping (pipping is the first hole a baby makes in the egg) they need to be in lockdown (don't move them) they need extra humidity so wet some kitchen roll with warm water and put the eggs on the kitchen roll trying not to change their position but make sure you do not cover any pips, ducklings take a long time to hatch up to 48 hours after the pip
@New duck mommy 2021 and
@WVduckchick can you give any more help
Also and this is important your family egg-napped those eggs, if they were covered then their mum was just out getting some food, water, having a swim and going to the toilet, and especially if they are alive
I don't know were you live but here in England it is illegal to take eggs from a wild bird you are only allowed to if you have a permit or are a wildlife rescue. I don't know whether your country has a different rule but it is wrong to steal a mother's babies whether you are allowed to or not
If you are worried about the eggs being abandoned then feel the eggs for if they are warm (if they are warm then mum is still looking after them) and you can also put 2 sticks as a cross on the eggs and then come back an hour or 2 later and see if mum is their or if the cross has been moved as you might scare mum off
Good luck
