How to Incubate & Hatch Chicken Eggs

A beginner's guide to hatching chicken eggs — incubator setup, temperature, humidity, turning, candling, and the 21-day timeline.

Hatching your own chicks is hugely rewarding. With a basic incubator and attention to a few numbers, most beginners get a good hatch from day one.

Before you start

You need fertile eggs — that means a rooster in the flock, or hatching eggs bought from a breeder. Store eggs pointy-end down, below room temperature, and set them within about a week for the best hatch rate.

Incubator settings

  • Temperature: 99.5 °F (37.5 °C) for a forced-air (fan) incubator; slightly higher for still-air.
  • Humidity: about 45–50% for the first 17 days, then raised to 65%+ for the hatch.
  • Let the incubator stabilize for a day before you set eggs.

Turning

Eggs must be turned to stop the embryo sticking to the shell — 3 to 5 times a day, or use an auto-turner. Stop turning on day 18 (“lockdown”) and raise the humidity.

Candling

Around day 7–10, hold a small bright light to each egg in a dark room. Developing eggs show veins and a dark embryo; clear eggs are infertile and can be removed.

The 21-day timeline

  • Days 1–17: incubate at temperature, turning daily.
  • Day 18 (lockdown): stop turning, raise humidity, and leave the lid closed.
  • Day 21: chicks pip and hatch. Leave them in the incubator until fluffy and dry — don’t help too soon.

After the hatch

Move dry, fluffy chicks to a brooder at 95 °F. Everything you need is in raising baby chicks. Want a no-tech option? A broody hen does all of this for you.
