Indian Runner Ducks - Day 26

[Spelnight]

Hi everyone,
I have 3 eggs in the incubator and expecting them to hatch in 2 days.
This morning when I woke up I saw that some foam was coming up from one of the egg? What does this mean? It's not smelly so I'm not sure.
Thanks

That's not a good sign I'd be keeping that egg away from the others, just in case. Have you been seeing any movement in it when you candle?

My fear would be that is has died and is now rotting and oozing, and eggs can and do explode.

Thank you for your reply, yes unfortunately it was rotten with an undeveloped duckling inside
I think I won't have any ducklings
