A new duckling/egg question

[chess0125]

Kind of an update on a previous post but a new question - Momma duck laid 15-20 eggs and has been sitting on them for 30 days now. Four ducklings have hatched total, one on Saturday/Sunday, three more yesterday (Monday) The rest of the eggs have no apparent holes (I didn't touch, just hovered over the nest) and they all have giant air sacks but I can't tell much more other than that. They seem to have a blue tint to them but that could just a shadow? I don't know, I'm new at this. There also seems to be an AWFUL smell coming from the nest area, I can't tell if it's rotten egg or a month's worth of momma duck poop. Will more hatch or is it just the four and a bunch of duds?? When will I know who's for sure they're not going to hatch and what do I do with any duds at that point?

yeah okay for the blue thing they lay blue or green tented colored eggs

as for the hatching when something hatches its gonna stink and when something is about to hatch it gets an odor to it . Also she could have been laying fertile eggs for over a 2 week period so there might be some babies that hatch out a lot later. when its safe to take eggs is when she is done with the nest and refuses to get back on it.

For now you should clean out the nest by takeing out the eggs shells of those that already hatched and any of the after hatch/ the brown stuff that is left after a duckling hatches
