Freaking out - day 40ish Muscovy eggs

[mganz42]

I've had one of my girls sitting on 16 eggs since may 20th or 21st. All 16 were fertile but most of them seemed to die late in incubation - there's no movement and the insides seem all... watery? Anyway, 5 or 6 of them are still moving around in there. I've been an anxious wreck since I thought they would hatch last week!

Here's one of the eggs:

No external pips.
