Roughly what day will bad eggs start smelling while incubating?

I am incubating 6 French black copper maran eggs, that were shipped to me. I am not able to see anything while candling them as they are very, very dark. Today is day 14. I am super scared of having a rotten egg explode in my incubator. I weighed them today to monitor weight loss and smelled every egg. None of them really have a scent at all, and I gave a very good sense of smell. No oozing or cracks either. Generally, if eggs have died or not developed would they start to stink by now? I’m worried about locking down a bad egg and having it explode.

Before an egg explodes, there would definatly be oosing of moisture and smell. I have never had an egg explode in my incubator.
Not even the guinea eggs i found in my orchard and placed in the incubator with no idea how old they were.
I think you should hold tight and continue your hatch.

I've never had a bad egg explode, I incubated goose eggs once and had a day 3-5 quitter in there the whole 35 days. It never exploded. It started to ooze towards the end though.

Thanks guys! I hate not being able to see anything when I candle! Literally going into this blind. I’ll just check for oozing right before lock down and give them a good sniff and go from there. Thanks!

Sounds good! I hope you have a great hatch! Post some baby pics in a few days
