Duck eggs exploding in incubator

[Newxxxduck]

so a little back story my ducks outside were nesting and she ended up killing 3 of her ducklings that hatched and I was able to save one. So after the third killing we brought the eggs inside to incubate. Last night I smelled something horrible to find out it was an egg that exploded when I looked at the duckling it looked fully developed. This morning when I turned them another egg was leaking and smelled very bad so I opened that one and it was a bad smell but no chick. About 5 minutes ago I’m sitting down heard a loud pop and the smell again. I go into the incubator and another egg popped! This duckling looked fully developed as well but the same smell came from it

What do you mean

Well, apparently they developed, but then died somehow, and are now rotting. That's what eggs do when they get really rotten. EXPLODE

Have you tried candling them?

What I was doing was commenting on your post to see what others had to say about what was happening to your eggs... since I have no experience or explanation for you.
