The time it takes for chicks to hatch depends on the bird species. Chicken eggs typically take 21 days to hatch, with some sources stating that it can take up to 24 hours for chicks to fully hatch. During the first 18 days, the eggs need to be turned 3-5 times a day, after which they are left alone for the final three days. The hatching process begins on day 18 when the chicks start to prepare to break out of the egg. On days 18 and 19, the chick positions itself with its head back and its beak towards the air sac, absorbing the rest of the yolk into its body for nourishment after hatching. On day 20, the chick pierces the membrane into the air chamber and breathes air for the first time. Newly hatched chicks may not need to eat or drink for at least 24 hours, as they absorb the remaining yolk sac before hatching. Duck eggs take 28 days to hatch, while goose eggs take 30 days.

What You'll Learn
The process takes 21 days
The process of hatching chicks takes 21 days. During this time, the eggs need to be carefully monitored and turned several times a day for the first 18 days, and then left alone for the final three days. The process of turning the eggs is important as it prevents the chick from sticking to the side of the shell.
On days 18 and 19, the chick positions itself with its head back and its beak towards the air sac, absorbing the rest of the yolk into its body to provide nourishment for the first few days after hatching. On day 20, the chick pierces the membrane into the air chamber and breathes air for the first time. It may also start peeping inside the egg.
On day 21, the chick will usually hatch. It can take up to 24 hours for the chick to completely hatch, although 5-7 hours is more common. The peeping of the newly hatched chick will encourage unhatched eggs to also start hatching. If there are still unhatched eggs at day 21, it is possible that timing or temperature was slightly off, so it is recommended to wait until day 23 before discarding the eggs.
Once the chicks have hatched and dried, they can be moved into the brooder, which should be set up and running at a temperature of 90-95o Fahrenheit. Food and water should be provided at this point. Chicks can survive for up to three days without food or water, but it is not recommended to wait longer than 24 hours before providing nourishment.

Eggs need turning for the first 18 days
Chicken eggs typically take 21 days to hatch. During this process, it is important to turn the eggs for the first 18 days of incubation. This is because the chalazae, or thin white ropy strands of protein in the egg, hold the yolk in place top to bottom, not side to side. By turning the egg, the embryo is swept back into the egg white, where there are fresh nutrients that help the chick develop. Turning the egg prevents the yolk from rising to the top and the embryo from being squashed between the yolk and the shell. It also prevents the embryo from sticking to the membrane, which can lead to reduced hatchability and chick quality.
Research has shown that egg turning is critical during the first week of incubation, especially the first three days. It is recommended to turn the eggs once toward each side of the incubator every hour, ensuring a consistent 43° to 45° turning angle at all times on both sides. This can be achieved by horizontally tilting the eggs or the trays (vertical setters) at a 43° to 45° angle from side to side. If turning the eggs manually, it is advised to gently mark each egg with a pencil to keep track of which eggs have been turned.
While some sources suggest that turning the eggs is necessary for the entire 18 days of incubation, others indicate that turning can be stopped after 10-14 days without negatively impacting hatchability. Stopping the turning process at this stage can improve airflow within the incubator and provide more efficient cooling for the eggs. Additionally, during the last three days before hatching, the chick gets into the hatch position, so it is recommended to stop turning the eggs at this point.
Overall, turning the eggs during the first 18 days of incubation is crucial for proper embryo development and hatchability. It ensures that the yolk remains centred and provides the necessary nutrients for the chick's growth.

Chicks need feeding immediately after hatching
Chicken eggs typically take 21 days to hatch. During the first 18 days, the eggs must be turned three to five times a day, and then they are left alone for the final three days.
Now, onto the question of whether chicks need feeding immediately after hatching. There are differing opinions on this. On the one hand, some sources say that it is not necessary to worry about feeding chicks as soon as they hatch. They can go a few days without eating, and it is important to let them fully dry off and wait for any other chicks to hatch before moving them all to the brooder. This natural process allows the first-hatched chicks to utilise their yolk reserves so that all chicks can begin feeding together, reducing the risk of predation by waiting for the protection of the mother and the rest of the group.
However, other sources emphasise the importance of providing food and water immediately after hatching to ensure optimal growth. Research has shown that when feed is withheld from chicks after hatching, there is a delayed growth curve compared to chicks that are fed immediately. These chicks will never catch up in terms of growth rate, and this lack of uniformity can cause issues within a housed group of chicks.
Therefore, while it may be beneficial to wait until all chicks have hatched to move them to the brooder, it is essential to provide food and water as soon as they are moved. This can be done by dipping the tip of each chick's beak into the water and then into the food to teach them where to find it. It is crucial to ensure that the correct food is provided, as layer ration, for example, can damage a chick's kidneys due to its high calcium content. Instead, a chick starter feed should be used until week 18 or when the first egg arrives.
In conclusion, while chicks do not need to be fed immediately after hatching, it is important to provide them with food and water as soon as they are moved to the brooder to ensure optimal growth and development.

Candling checks embryo growth
Chick embryo development takes about 21 days from start to hatch. During this time, the embryo undergoes rapid growth and several changes. The practice of candling chicken eggs provides valuable insights into the intricate process of embryo development. It involves shining a light through the eggs to monitor their development and identify potential issues.
Candling chicken eggs at different stages of development can reveal fascinating insights. On day 7, a fertile egg typically shows a small dark spot, indicating the presence of the embryo, along with red veins branching out and a visible air sac. Some movement may even be visible. If veins or an air sac are absent, it suggests that the egg isn't developing.
On day 14, a healthy chick embryo should occupy most of the egg, resulting in a darker interior and reduced light passing through. If there is little change from day 7 or the egg still appears clear, it indicates that the embryo may have stopped developing, and the egg should be removed. These two candling sessions offer the clearest view of embryo development and help assess the viability of the eggs.
While candling is a valuable tool, it is important to avoid excessive disturbances during critical periods of embryo development, especially in the early days when the network of blood vessels is delicate and susceptible to disruption. Additionally, the last few days before hatching are not recommended for candling, as the chick moves into position for the hatch and fills most of the shell, making it challenging to observe significant details.
In summary, candling checks are crucial for monitoring embryo growth and development during the 21-day incubation period. By shining a light through the eggs at specific intervals, such as days 7 and 14, individuals can assess embryo viability, identify potential issues, and make necessary adjustments to ensure a successful hatch.

Hatching can begin any time
The process of hatching chicks requires care, vigilance, and planning. Chicken eggs typically hatch after 21 days in an incubator, with the hatching process often commencing on day 18. However, it's important to note that the timing may vary, and some chicks may take up to 24 hours to completely hatch, although 5 to 7 hours is more common.
Hatching can begin at any time, and the process is not limited to a specific time frame. The initiation of hatching depends on various factors, including the time of day the eggs are set. If the eggs are set in the evening, hatching tends to begin in the evening, whereas if they are set in the morning, hatching starts in the morning. The hatching process can span a day or two, and it's not uncommon for some chicks to hatch a day earlier or later than the rest.
To ensure a successful hatch, it is crucial to maintain optimal temperature and humidity conditions within the incubator. Opening the incubator should be avoided as it can disrupt the crucial heat and humidity levels. Turning the eggs several times a day during the first 18 days is essential, after which they should be left undisturbed for the final three days.
The hatching process is a delicate one, and newly hatched chicks may appear weak and exhausted. They gradually dry out and become active within a few hours. It's important to provide food and water once the chicks have dried, and they can be moved to the brooder, which should be maintained at a temperature of 90-95° Fahrenheit.
Hatching chicks can be a rewarding experience, but it requires proper planning and equipment. It's essential to test all equipment before receiving the fertilized eggs, and the brooder should be prepared in advance. Additionally, it's important to be aware of local ordinances regarding roosters and have a plan for rehoming if necessary.
