Frequently Asked Questions
The most common questions about incubation and chick care.
How long does it take for eggs to hatch?
Chicken eggs hatch in about 21 days. It varies by species: quail around 17–18 days, ducks about 28, geese about 30. Check the species page for the exact time.
Do you need a rooster for eggs to hatch?
Yes. Only fertilised eggs hatch, and fertilisation needs a rooster. A hen lays regularly without one, but those eggs will never hatch a chick.
Can you hatch eggs without an incubator?
Yes, with a broody hen sitting on the eggs. An incubator just gives more consistent temperature and humidity, especially for larger batches.
How often should you turn the eggs in an incubator?
Without an automatic turner, turn them at least 3 and ideally 5 times a day. Use an odd number so the eggs don’t rest on the same side every night, and stop turning at lockdown.
What temperature and humidity do hatching eggs need?
For most poultry, about 37.5 °C and 45–55% humidity, raised to 65–75% for the last few days (lockdown). Exact values vary by species — see the species page.
Why didn’t my eggs hatch?
The most common reasons are infertile eggs (no rooster), unstable temperature or humidity, too little turning, or eggs that were too old or badly stored before setting. Candling around day 7 helps you spot problems early.
When and how do you candle eggs?
Hold a bright light to the egg in a dark room, usually on days 7 and 14 and just before lockdown, to check whether it is fertile and developing.
What temperature do newly hatched chicks need?
Keep the brooder around 35 °C in the first week and lower it by about 3 °C each week until they are fully feathered.
