Do you start with a cold or warm incubator?

Ok so the consensus is that putting eggs in a warm incubator should not cause a problem? I wonder if I had a temp spike that I wasn't aware of? It's just heartbreaking...out of five dozen eggs I put in there are *maybe* four still wiggling. (One for sure.) I hope they hatch!

I’m getting a Bluetooth hydrometer to help keep me updated with my temps & humidity bc I’m afraid of this as well!
