What to write down
- Temperature and humidity at the same time each day, from a second thermometer if you have one.
- Turning, or that the auto-turner is running; when you stop turning at lockdown.
- Water added and vent changes.
- Candling results: veined, clear, stopped (blood ring).
Hatch rate
The summary shows chicks hatched as a share of eggs set and of eggs still developing at candling. The second number says more about your incubator; the first also reflects fertility and egg storage.
