📋 General guidance

• Total incubation: 21 days for chicken eggs.
• Temperature: ~37.5°C in a forced-air incubator.
• Humidity: 50% for days 1–18, then 70% for days 19–21 (lockdown).
• Turn eggs an odd number of times a day (3-5) so they don't rest on the same side two nights in a row. Stop turning at day 19 for lockdown.

These are common starting points — follow your incubator's manual if it differs.
