1. The egg incubation cycle is affected by the incubation temperature. The higher the incubation temperature given to the chicken, the shorter the egg incubation cycle, and conversely, the lower the incubation temperature given to the chicken, the longer the egg incubation cycle. However, the incubation temperature of chickens is not said to be nonsense, and it should be kept between 36~40 °C.
2. Let the hen hatch the eggs in the natural state, and the chick will break out of the shell after 21 days of incubation. However, due to factors such as the height of pseudo-incubation temperature and the size of the eggs, it is common for hatchers to hatch after 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. The test shows that the incubation temperature of chickens is between 36~40 °C. The higher the incubation temperature, the shorter the incubation cycle, if the incubation temperature given to the eggs is kept at 39 °C for a long time, the hatch will be hatched after 19 days; Low incubation temperatures can lead to longer incubation processes, sometimes even more than 22 days before hatching occurs. However, in both cases, hatchability and chick quality were poor.
4. Summarizing these phenomena, scientists have found that the humidity and temperature in the incubation process is a gradual accumulation process. Within a certain temperature range, when the accumulated incubation temperature reaches a certain value, the embryo matures and breaks out of the shell.
5. 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, under normal incubation, the accumulated temperature of 37 °C during the whole incubation process is roughly between 18700~19000 °C; The incubation time is 492~506 hours. Converted to an hourly incubation temperature, it is about 37.5~38°C.
6. This temperature range is the reference value of the egg temperature to be given when we hatch. 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 best 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.
