Chicken eggs take around 21 days to hatch. The process requires an egg incubator to help control temperature, humidity, and egg turning. The eggs need to be turned once a day for the first 18 days and then left alone for the final three days. The humidity should be kept at 50-55% for the first 18 days and then increased to 65-70% for the last three days. The temperature should be set to 100.5 degrees Fahrenheit.

What You'll Learn
Chicken eggs take around 21 days to hatch
To hatch chicken eggs, you will need an egg incubator to help control temperature, humidity and egg turning. The incubator should be cleaned with a 10% bleach solution, followed by warm soapy water and a thorough rinse. It should then be placed in an area with a steady ambient temperature and no risk of drafts. The temperature and humidity inside the incubator are critical factors for successfully hatching eggs. The ideal temperature is 100.5 degrees Fahrenheit with 50-55% humidity for the first 18 days. For the last three days, the humidity should be increased to 65-70% and ventilation should be increased.
During the first 18 days, the eggs must be turned 3-5 times per day to prevent the chick from sticking to the side of the shell. Newer incubators have an egg-turner that does this automatically. After 18 days, the eggs should be left alone for the final three days to allow the chick to position itself for hatching inside the egg.
By day 18, the embryo has developed into a chick and will take up most of the space in the egg. Blood vessels in chicken eggs are normally observable within 7 to 10 days of incubation, and by day 18, the embryo takes up most of the egg and appears as a dark area within it.

Eggs must be turned for the first 18 days
The process of incubating chicken eggs takes 21 days. During this time, the egg must be turned regularly, especially during the first 18 days of incubation. This is because the embryo rests on top of the egg yolk, and turning the egg prevents the embryo from being squashed between the yolk and the shell and sticking to the shell membrane.
The egg must be turned side to side, not end to end, and rotated 180 degrees. This is important to keep the yolk centred in the egg. The chalazae, or thin white ropy strands of protein in the egg, hold the yolk in place top to bottom, not side to side, which is why the egg must be turned side to side.
Turning the egg is most important during the first week, before the chick's circulation system is developed. After 18 days, the embryo has developed into a chick and will take up most of the space in the egg. At this point, the egg turning can stop, and the chick will position itself for hatching inside the egg.
The minimum recommended number of turns per day is three, but five turns per day is better. An odd number of turns per day is important so that the egg is sitting on the opposite side each night. This is because the egg will be sitting in the same position for a 12-hour period, so it is important that it alternates sides each night.

Humidity is critical for hatching eggs
The incubation period for chicken eggs is 21 days, and temperature and humidity are critical factors in the success of the hatch. In nature, the mother hen provides the optimal incubation environment for the embryonic development of her eggs. She instinctively fine-tunes the temperature, oxygen, and humidity levels for her eggs.
Similarly, in commercial incubation, hatching eggs have the same needs. They require the correct temperature, CO2/O2 concentration, humidity, and turning angle. Modern ventilation control systems inside setters and hatchers can automatically adjust the humidity levels by monitoring the CO2 levels inside the incubator. This ensures that the correct air volumes, conditioned in terms of temperature and humidity, are delivered to the setter and hatcher room at all times.
All avian eggs lose water through the pores in the eggshell during incubation. This water loss is necessary for the embryo to generate a healthy air cell size to inflate its lungs after internal pipping. The higher the humidity level surrounding the eggs, the lower the water loss rate. Therefore, the humidity levels determine the rate at which the hatching eggs lose water and, consequently, weight. If the air cell is too small due to insufficient water loss, the embryo's lungs cannot fully inflate, and the chick will not be able to obtain enough oxygen for the hatching process. On the other hand, excessive water loss can cause embryo dehydration.
Thus, maintaining the proper humidity levels during incubation is critical for achieving optimal hatchability and chick quality. The suggested humidity levels during the first 18 days of incubation are between 50% and 55%, while the humidity should be increased to 65%-70% for the last three days.

Embryos develop in 7-10 days
Chicken embryos develop in 7-10 days. At this stage, you may be able to observe blood vessels within the egg, indicating that the embryo is alive. By 18 days of incubation, the embryo takes up most of the egg and appears as a dark area within it. You may even be able to see movement inside the egg at this point.
To ensure the embryo develops, the eggs must be stored at a temperature between 12 and 14 °C and a humidity of 75 to 85 percent. They should be stored for no longer than seven days. After this, the eggs can be placed in an incubator, which should be set to a temperature of 100.5 °F and a humidity of 50-55%. The eggs must be turned regularly during the first 18 days of incubation to prevent the embryo from sticking to the shell.
The development of the embryo is a delicate process, and the temperature and humidity levels must be carefully monitored. A well-ventilated incubator will prevent any toxic fumes from harming the embryo. A human clinical thermometer can be used to ensure the incubator is maintaining the correct temperature.
By day 18, the embryo has developed into a chick and will take up most of the space in the egg. At this point, the chick is preparing to hatch, and the egg turning can be stopped. The eggs should be left alone for the final three days, during which time the humidity should be increased to 65-70%. The chicks will likely hatch on day 21 but can take a couple of days longer.

Fertile eggs are required for hatching
Chicken eggs take approximately 21 days to hatch. To begin the process of hatching, fertile eggs are required. These can be collected from hens housed with a rooster. The presence of a rooster in the flock is essential for obtaining fertile eggs.
Fertile eggs can be identified by a small bullseye shape on the yolk, which is a cluster of cells that can develop into a chick. However, this is difficult to discern without cracking the egg. Another method is "candling", which involves shining a light through the eggshell in a dark room after about a week of incubation. If there is a dark shape inside the egg, it indicates the presence of a developing embryo, confirming its fertility.
It is important to source fertile eggs from a National Poultry Improvement Plan (NPIP)-certified flock to minimize the risk of disease. Prior to incubation, these eggs can be stored for up to 7 days in a cool, draft-free environment at a temperature of 55-60°F (12-14°C). The ideal humidity range for storage is 75-85%.
Once the eggs are placed in the incubator, the temperature and humidity levels become critical for successful hatching. The incubator should be set to maintain a temperature of 100.5°F with 50-55% humidity for the first 18 days. During the final 3 days, the humidity should be increased to 65-70% to facilitate hatching. Additionally, ventilation should be increased as the embryos grow, especially from days 18 to 21.
