Watching a chick break out of its shell is an exciting experience. This process, known as hatching, sees a chick break through its shell and take its first breath of air. It is generally advised not to intervene in the hatching process, as it can lead to adverse outcomes for the chick, including death. However, in certain cases, intervention may be necessary, especially if the chick is malpositioned or has a weak constitution. If intervention is required, it should be done with extreme caution and care, as it can easily lead to more harm than good.

What You'll Learn
The role of the egg tooth
The egg tooth is a small, sharp protuberance found on the beak of a baby chick. It is a temporary adaptation, falling off within a few days of hatching, or being absorbed into the chick's bill as it grows. The egg tooth is used to break through the eggshell during the hatching process.
As the chick develops inside the egg, it uses its egg tooth to make a small hole in the eggshell, or "pipping". The chick taps furiously with its egg tooth until it breaks free. The hole made by the pecking beak gradually expands until it zips and breaks through. This process can take up to 18 hours.
The egg tooth is an important adaptation that allows chicks to hatch from their eggs more easily. Without it, some chicks may get stuck to the dried membrane inside the shell, which can lead to bleeding and even death. It is generally advised not to intervene in the hatching process, as doing so can cause harm to the chick.
In some cases, such as with kiwi birds and megapodes, the egg tooth is not required for hatching. These birds are strong enough to use their legs and feet to crack open the egg.

Why chicks shouldn't be helped out of their shell
The process of a chick breaking out of its shell is called hatching. On day 20, the chick pokes a hole in the membrane holding it inside its shell and starts making peeping sounds. On day 21, the chick starts to break out of its shell using its egg tooth. This process is known as pipping.
While it may be tempting to help a chick break out of its shell, it is generally not recommended to intervene in the hatching process. Here are several reasons why chicks should not be helped out of their shells:
Risk of Bleeding and Death:
The most significant risk of assisting a chick during hatching is causing it to bleed to death. The chick's blood vessels are still developing, and if they are ruptured during the process of removing the chick from the shell, it can lead to fatal bleeding. It is a delicate procedure that requires extreme caution.
Potential for Deformities and Health Issues:
Interfering with the natural hatching process can increase the risk of deformities and health issues in the chick. In some cases, assisted hatching may result in wing deformities or other physical abnormalities that can impact the chick's long-term health and quality of life.
Leg Strength Development:
The process of breaking out of the shell helps chicks develop leg strength. By allowing them to push and work their way out, they build the necessary muscle strength to support their bodies. If they are helped out too soon, they may have weaker legs and struggle to walk or stand firmly.
Commitment to Special Needs Care:
If a chick is struggling to hatch and requires assistance, it may be an indication of underlying health issues or disabilities. Helping such a chick to hatch means committing to the possibility of long-term care for a special needs chicken. This includes potential veterinary visits and ongoing support to maintain the chick's health.
Humidity Concerns:
Opening an incubator to assist a chick can cause a loss of humidity, making it more challenging for other chicks to escape their shells. It can create a ripple effect, requiring further interventions and potentially impacting multiple chicks' hatching processes.
While it can be challenging to refrain from helping, it is crucial to trust the natural hatching process and only intervene in rare and informed circumstances.

How to help a chick out of its shell
It is generally advised to avoid intervening in the hatching process of chicks. However, if a chick has not emerged from its shell after 24 hours of pipped incubation, it may be stuck to the dried membrane inside the shell due to insufficient humidity. In such cases, you may carefully assist the chick by following these steps:
Prepare the Environment:
- Ensure the chick is peeping and active, indicating it is alive and healthy.
- Create a warm and humid environment by steaming up a small enclosed space, such as a bathroom. This helps maintain moisture during the process.
Assist the Chick:
- Use a Q-tip with liquid coconut oil to gently lubricate the dried membrane, making it easier for the chick to move.
- Carefully pip the egg, mimicking the natural process, and then return the egg to the incubator.
- Allow the chick to continue the hatching process independently. Intervene only if necessary, gently breaking away small portions of the shell to avoid damaging the chick or causing bleeding.
Post-Hatch Care:
- Provide the newly hatched chick with additional time in the incubator to gain strength before joining the rest of the flock.
- Be prepared to offer long-term care if the chick has any special needs or disabilities due to the assisted hatching process. This may include regular veterinary visits to maintain its health.
Remember, assisting a chick in hatching is a delicate process that carries risks. It is important to carefully consider these risks and be prepared to provide any necessary care for the chick's well-being.

The hatching process
On day 20, the chick pecks a hole in the membrane holding them inside their egg and starts making peeping sounds. On day 21, they start to break out of their shell using their egg tooth, a hard white object on the beak of an embryonic bird, which is lost later on. The chick taps furiously on the shell with its egg tooth until it breaks free. This process of creating a small crack on the surface of the eggshell is called "pipping" and can take up to 18 hours. Once the chick pierces the membrane and breathes air from the air chamber for the first time, you may hear peeping.
After pipping, the chick will quietly rest, breathe oxygen, and complete the final stages of its development. This rest period is crucial, as the chick absorbs the remaining yolk, which provides essential nutrients and energy for the final push. The timing of a chick's hatching is not always predictable and can depend on various factors such as the age of the eggs, the health of the mother hen, and fluctuations in temperature during incubation. Some chicks may hatch before 21 days, while others may take longer.
During the hatching process, known as "zipping," the chick makes tiny cracks around the egg in a counter-clockwise direction until it can push itself out of the shell. Unzipping usually happens quickly, but it is important to be patient as rushing can harm the chick. If a hatch is taking excessive time, there may be something wrong with the chick, such as health issues or developmental delays, and intervention should be done with extreme caution.
If the conditions in the incubator are right, it can take up to 24 hours for a chick to escape the egg after pipping, and this is perfectly natural. However, if the humidity is too low during incubation, the membrane inside the egg may dry out and become tough, making it difficult for the chick to zip effectively. In such cases, intervention may be considered, but it should be done very carefully to avoid causing bleeding or other damage to the chick.

How long does hatching take
The process of hatching is a complex and fascinating one. On day 20, the chick pecks a hole in the membrane holding it inside the eggshell, using its egg tooth, a hard white object on the tip of its beak. This process is known as pipping. After pipping, the chick will take a break before starting to break out of its shell. This can take between 12 and 24 hours, with 5-7 hours being the most common timeframe. However, some sources say that this process can take up to 18 or even 24 hours.
Once the chick has rested, it will begin to rotate and kick inside the egg, breaking the shell and freeing itself. This stage of the process is called unzipping. It is important to note that the timing of a chick's hatching is not always predictable and can depend on various factors, such as the age of the eggs, the health of the mother hen, and fluctuations in temperature during incubation. Some chicks may hatch before 21 days, while others may take longer.
While it can be tempting to assist a chick in hatching, it is generally not recommended. Intervening in the hatching process can be dangerous, and it is best to let nature take its course. If a chick is taking an excessive amount of time to hatch, it could be a sign that something is wrong, and it may require special care if it does hatch. However, with proper care and vigilance, you can successfully hatch healthy chicks at home, a rewarding experience for chicken raisers.
