Haha, sorry for the confusion guys. Yes, the due date is now the 15th. I decided to give the eggs another week since my mind basically blew up one day and though they'd hatch on the 8th, but I now realize now that that was 21 days, not 28. cluckcluckluke, once you said it was 28 days for ducks I was falling asleep thinking about ducklings but just as I was about to sleep, I realized "Wait, that's a week BEFORE they should hatch!", but sadly my computer crashed and would not start so I decided to head to bed.
No, they have not hatched yet. However last night I was candling one and it had a LOT, and I mean A LOT, of movement. It also had a little nub looking thing kinda poking the airsac. It might just have been stretching or something, but it looked like something might have been trying to breath. And one question, do eggs sleep? It might sound like a stupid question but I just want to clarify this.
