If the incubator's temperature spikes, can this cause ‘exploding eggs’?

A spike or rise in incubator temperature does not  cause exploding eggs.

If you have experienced ‘exploding eggs’ in your incubator, neither the incubator nor the temperature at which the incubator is operating will have caused this. 

Exploding eggs is caused by ‘bad eggs' and the reasons for exploding eggs can be narrowed down to one of these factors:

• Dirty eggs from nest
• Eggs not washed properly
• Water condensation on eggs
• Water sprayed on eggs
• Contamination from earlier exploders
• Contaminations from handling with dirty hands

'Exploding eggs' occurs because of a build-up of gas- a bacterial byproduct - within the egg.  Once enough gas builds up inside the egg, the internal pressure becomes too great and the egg explodes.

For more information on exploding eggs and other possible causes of failed hatches, we have a trouble-shooting guide which can be found here.
