Successfully Incubating Eggs: Tips for a Healthy Hatch

Incubating eggs is a fascinating and rewarding process that allows you to witness the miracle of life firsthand. Whether you're hatching eggs for a backyard flock, preserving a rare breed, or simply experiencing the joy of raising baby chicks, successful incubation requires careful planning, attention to detail, and patience. With the right equipment, proper environmental conditions, and a little dedication, you can significantly increase your hatch rate and ensure healthy chicks. In this guide, we’ll walk you through everything you need to know about incubating eggs—from selecting the right ones to providing the best conditions for a successful hatch.

Choosing the Right Eggs

Selecting the right eggs is the first step toward a successful hatch. Fertilized eggs should come from healthy, well-fed parent birds to ensure strong embryo development. When choosing eggs, look for ones that are clean, well-formed, and free of cracks or abnormalities, as misshapen or damaged eggs may have lower hatch rates. Freshness is also crucial—eggs should ideally be no more than seven days old before incubation, as fertility declines over time. Store them in a cool, humid place (around 55°F with 75% humidity) and position them with the pointed end facing downward to keep the embryo in the best condition. Avoid washing eggs, as this can remove their natural protective coating, which helps prevent bacteria from entering. By starting with high-quality eggs, you give your hatchlings the best possible chance of success.

Choosing and Preparing the Right Incubator

Choosing the right incubator is essential for maintaining the ideal environment for embryo development. There are two main types: still-air and forced-air incubators. Still-air models rely on natural heat circulation and require slightly higher temperatures (around 101-102°F), while forced-air incubators use fans to evenly distribute heat, maintaining a consistent 99.5°F. When selecting an incubator, consider features such as automatic egg turners, built-in thermometers, and humidity controls, which can make the process more efficient and reliable.

Size is another factor—smaller incubators are great for beginners, while larger models are better suited for hatching multiple eggs at once. This incubator has been our favorite and has hatched consistently for multiple seasons! No matter which type you choose, it’s crucial to test and stabilize the incubator before placing eggs inside, ensuring proper temperature and humidity levels for a successful hatch.

Additionally, proper preparation is key to ensuring a smooth incubation process. Before placing eggs inside, thoroughly clean and disinfect the incubator to eliminate bacteria that could harm developing embryos. Once clean, set the incubator to the correct temperature and humidity—99.5°F for forced-air models and 101-102°F for still-air models, with humidity around 50-55% for the first 18 days. It’s crucial to let the incubator run for at least 24 hours before adding eggs to ensure it maintains stable conditions. Also, placing the incubator in a draft-free, temperature-controlled room away from direct sunlight or vents can help prevent fluctuations.

Placing the Eggs and Monitoring the Incubation Process

Once the incubator is ready, carefully place the eggs inside, ensuring they are positioned correctly—either lying on their sides or with the pointed end facing downward. Eggs must be turned regularly to prevent the embryo from sticking to the shell, which is why automatic turners can be a helpful addition. If turning manually, rotate the eggs at least three to five times a day, marking each side with an "X" and "O" to keep track. Consistency in turning is vital until day 18, when the lockdown phase begins. Throughout the process, avoid sudden movements or excessive handling, as this can disrupt development.

Monitoring the incubation process is crucial for maintaining stable conditions. Temperature should remain constant, and humidity levels should be carefully adjusted—too high or too low can impact hatch rates. Ventilation is also important, as embryos need oxygen to develop properly. Candling, which involves shining a light through the eggs, should be done around days 7 and 14 to check for signs of development. Healthy embryos will show visible blood vessels and movement, while clear or irregular eggs may be infertile or non-viable and should be removed to prevent contamination. By carefully maintaining the right conditions and monitoring progress, you increase the chances of a successful hatch.

Lockdown Period (Days 18-21)

The lockdown period, which begins on day 18, is a critical stage in the incubation process. At this point, egg turning should be stopped to allow the chicks to position themselves correctly for hatching. Humidity levels should be increased to around 65-75% to prevent the inner membrane from drying out, which can make it difficult for chicks to break through the shell. It’s essential to avoid opening the incubator during this time, as sudden drops in humidity can cause complications like shrink-wrapping, where the chick becomes stuck inside the membrane. Instead, focus on maintaining stable conditions and watching for signs of hatching, such as movement, chirping, or external pipping. Patience is key—chicks may take up to 24 hours to fully emerge from their shells after the first pip. Creating a stress-free and undisturbed environment during lockdown gives the chicks the best chance of hatching successfully.

Hatching and Post-Hatch Care

Hatching is an exciting but delicate process, requiring patience as the chicks work their way out of their shells. The first sign of hatching is external pipping, when the chick makes a small crack in the shell. This can be followed by a process called "zipping," where the chick gradually pecks around the shell to break it open. While it may be tempting to assist, it’s generally best to let chicks hatch on their own unless they are struggling for an extended period. Intervening too soon can cause bleeding if the chick has not yet absorbed all of its blood supply from the membrane, which can be fatal. 

Once hatched, chicks should remain in the incubator for several hours to dry off and gain strength before being moved to a brooder. The brooder should be pre-warmed and equipped with a heat source, soft bedding, clean water, and chick starter feed. It isn’t absolutely necessary, but I will sometimes add a supplement such as this to their water for the first 3 days to give an extra boost, especially if there are any complications during the hatching process. Ensuring a smooth transition from the incubator to the brooder sets the stage for healthy growth and development in the crucial first days of life.

Final Thoughts

Successfully incubating eggs is one of the most rewarding experiences on the farm, offering a front-row seat to the miracle of new life. While it does require careful attention and a bit of patience, the moment you hear that first tiny peep or see a damp, wobbly chick emerge from its shell, every careful step becomes worth it. Remember, no hatch is ever perfect—nature can be unpredictable—but with the right preparation and a gentle touch, you can create the best possible environment for your future flock.

Whether you're growing your backyard chickens, preserving rare breeds, or simply soaking in the wonder of it all, I hope this guide helps you feel more confident and excited about your own hatching journey.
