I'm sure you are doing fine. It is always stressful. My normal routine isn't really a lot different than what I'm doing here, excel put my normal incubator has a much better temperature control system, I monitor humidity and keep it in a more controlled environment (the basement). I also normally use a educated hatcher without a fan.
That is one of my big concerns here, the fan. I can't turn it off.
I have used this incubator twice before. Once I just threw some excess quail eggs in since I had nowhere else to put them and got a 50% hatch. Last year someone borrowed it so their kids could watch eggs hatch. It wasn't monitored and the temperature was never checked. It was left at factory default which appears to be wrong by -2°C. They still got 2/24.
It's amazing what can happen.
