The Egyptians used to have a traditional method of incubating eggs during 400 BC, by using a cylindrical shaped building or oven that had a fire at the bottom.

Eggs were covered in an inverted cone by partially covered in ash. The eggs were used to be kept on a woven basket at the top of ashes. The roof of the building let the smoke escape and prevent rain from coming inside.

Controlled scientific incubation requires an accurate temperature range to function properly and to do so; the alcohol-based thermometer is used. It was made by the French naturalist and scientist René Antoine Ferchault de Réaumur in 1730, and hence the temperature scale is also named after him.

Réaumur used the thermometer in his design for an artificial incubator, which was presented to the Académie des sciences in 1747 and was published in 1749.

It was published as “The art of hatching and rearing the domestic birds of all species and in all seasons, either using the heat of manure or by ordinary fire”.

Lyman Byce created a coal lamp incubator in the year 1879. The first commercial machine was made by Hearson in 1881.

Ira M. Petersime of Gettysburg, Ohio, USA invented the electric egg incubator in the year 1922. After that, he and his son manufactured the best incubators for chickens. They were granted with several patents of design features and other improvements.

The innovation of an electric incubator with expanded capacity offered a model that held 15000 eggs, and this encouraged the growth of large-scale commercial hatcheries.

First, a hen lays her eggs. Then after that, she sits on eggs for 21 days to give them proper temperature for hatching. This process is called natural hatching.

During this period hen moves and turns her eggs using her beak and body for giving equal heat to all sides of eggs.

Hen gives her body heat by sitting for 21 days on the eggs and after that chicks came out of the eggs.

When the chicks come out from eggs, they take the heat by going below the hen’s wings. It is called natural brooding which is helpful for initial growth and development of baby chicks.

Sometimes, few hens won’t sit on their eggs those hens are called non-broody hens. After that they start mating again. This occurs mostly in egg laying chickens.

In those type of situation you need to use artificial brooding methods. Here is our complete guide on brooding chickens.

But, nowadays lots of egg hatcheries are using incubator to hatch millions of eggs in a single time. After hatching they deliver those chicks to chicken farmers.

But If, you are a small farmer or you are passionate about hatching eggs at home then follow the steps below.

Step 1: Select Eggs for Hatching

The selection of eggs in the hatching process is very important. Always take high-quality eggs for a top hatching rate. If you are taking eggs from your backyard chicken farm, make sure the eggs are clean, fresh, and undamaged.

If you have bought from somewhere else, keep the eggs for 24 hours (1 day) to relax before keeping it inside the incubator. Check all eggs before keeping them on the farm.

Do not keep the egg for over 10 days because after that the hatching rate of the eggs gradually decreases. Also, keep them in a cool place but not inside a refrigerator. Turn the eggs once a day to keep the egg yolk in the center. Do not wash the eggs.

Step 3: Maintain Your Incubator Temperature and Humidity

Then keep your chicken eggs inside the incubator. There are two types of incubator forced air and still air incubator.

The difference is only a fan. In forced air incubator fan blow air inside the incubator to make the temperature constant everywhere but in still air egg incubator, the temperature increases gradually to fill inside the incubator. But if the incubator provides automatic turning of eggs then its a great thing.

So, in forced air incubator the temperature should be maintained between 99.5-100°F and in a still air incubator 101–102°F. Most of the incubator companies tell to keep 45-50% humidity for the first 18 days of incubation and then 60-70% for rest days.

Step 4: Checking the Egg Fertility and Candling Method

During the incubation period, it is better to check, the fertility of eggs. Natural fertility may defer from season to season. In the summer season if eggs have 40-60% of fertility rate if eggs kept for a long time before hatching.

But in winter the fertility is about 70-80% but it may take 1-2 days more for hatching due to cold temperature. In the rainy season, it is about 70-90%.

But in an artificial incubator, the outside temperature doesn’t affect the fertility rate due to its automatic humidity and temperature control features.

In most of the chicken eggs, embryo development starts after a week of incubation. You can see it by doing candling. You will see little veins and embryo structures inside the egg.

If you didn’t see any development and changes within 9-10 days replace those eggs from fresh eggs.

You can put a date on eggs to overcome the confusion of messing up older eggs with fresh eggs if you are replacing any new egg. During candling, you will see blood rings and veins inside the eggs. It shows that the embryo is developing.

Step 4: Turning and Lockdown period

Turning of chicken eggs must be done for about 14-15 days. The first two weeks are most important for proper turning. But, you can turn them for 17-18 days during incubation. The last 3 days before hatching is called the Lockdown period.

You should not turn the egg during the last three days. If it is an automatic machine – switch off the turning process but not the incubator. Also, increase the humidity level to 65-70%.

Step 5: Hatching of eggs and moving chicks

You will see the hatching of eggs starts after day 21 or 22. Do not remove the chicks out from the incubator still they look completely dry and puffed (soft and puffier).

Newly hatched eggs can easily live for 2-3 days without eating anything. They live due to the eaten yolk during the incubation period.

After that chicks are ready for brooding. Make sure to keep chicken waterer and feeder inside your brooder area before transferring them.
