How long does it take to hatch an egg?

1. The egg incubation cycle is affected by the incubation temperature. The higher the incubation temperature given to the chicken by the user, the shorter the egg incubation period, and the lower the incubation temperature given to the chicken by the user, the longer the egg incubation period. However, the incubation temperature of chickens is not to say that it is random, and it should be kept between 36 and 40 degrees Celsius.

2. Let the hens incubate the eggs in a natural state. Usually, the chicks will hatch after 21 days of incubation. However, due to factors such as the pseudo-incubation temperature and the size of the eggs, it is also common to hatch for less than 21 days or more than 21 days. Therefore, the incubation temperature of chickens is an important factor affecting the incubation cycle of eggs.

3. Tests show that the incubation temperature of chickens is between 36 and 40 °C. The higher the incubation temperature, the shorter the incubation period. If the incubation temperature of the eggs is kept at 39 °C for a long time, the eggs will hatch in 19 days; if the incubation temperature is low, the incubation process will be prolonged, and sometimes it will take more than 22 days. young. However, hatchability and chick quality were poor in both cases.

4. Summarizing these phenomena, scientists found that the humidity and temperature during incubation is a gradual accumulation process. Within a certain temperature range, when the accumulated incubation temperature reaches a certain value, the embryo will mature and hatch.

1. In order to achieve the ideal incubation effect, we must not only meet the accumulated temperature requirements of the entire incubation process, but also ensure that the incubation time is normal. Generally speaking, for normal incubation, the accumulated temperature at 37°C during the entire incubation process is roughly between 18700 and 19000°C; the incubation time is 492 to 506 hours. Converted to the incubation temperature per hour, it is about 37.5~38 °C.

6. This temperature range is the reference value of the egg temperature we need to give when hatching. In actual production, we can make appropriate adjustments according to different incubators, different environmental conditions, and different egg conditions.

7. The eggs used for hatching are preferably within a week, otherwise the longer the storage time, the lower the hatching rate, and the health of the hatched chicks will also be affected.
