Found a stash of eggs

I have one 7th month old Muscovy that just successfully sat and hatched baby ducklings. She picked a nest box in the coop and sat from the time she laid her first egg til they hatched.

I have 2 other girls the same age - haven't gotten eggs from either for a bit. The other day found a stash in corner of a shelter. Will one go back and start sitting on these eggs? there were 14 eggs yesterday. I think she sits on them at night but pays no attention to them during the day. She just adding them up to sit or is that anyone's guess whether they will start brooding them?


thanks
