Never had this happen. I'm hearing that is was just a bad egg that filled up with gas and combusted so Im not too worried but had to share because I was shocked! Got 2 eggs left....we'll see!
You HAVE to remove bad eggs before this happens. Your incubator is now contaminated, full of bacteria, fungus, sulfer dioxide,and whatever else grows on rotten eggs.
I removed the egg as soon as I saw what had happened. Before it exploded it looked beautiful! Pure white, No mold, dents nothing. Yes the mess was smelly and gross. I removed all the other eggs into a different incubator and scrubbed the yucky one pretty good. Still smells...
Well the egg was about a month old. And the two that are left, one is a week earlier and the other one came a week after so.., we will see what happens. Their due in/around Feb. I cleaned the incubator with Dawn and warm water and now have a cup of baking soda inside with the door shut to eliminate any more of the odor that is still linguering. Sorry to hear about your eggs
Oh cool idea with the baking soda...my flatmate puts it in our fridge when I have mealworms in there for the lizards (apparently that's gross ).
Good luck with the rest of the clutch.
