(1) Embryo growth was inhibited below 23.9 degrees (physiological zero) and began to grow above 23.9 degrees. For example, the temperature of eggs should be 15.5-25℃ for one week and 12- 18℃ for more than one week. The suitable humidity is 70% to 80%.

(2) It is best to store eggs with their heads down, and the storage time should be within 7 days. The sooner you hatch, the better. Prolonged storage time will lead to a decrease in hatching rate.

2. Culture temperature:

The ideal temperature of twelve days before hatching is slightly higher than that of two days after hatching. The suitable temperature for the first 12 days is between 37.5 and 37.7 degrees Celsius, and the optimum temperature for the last two days is between 36. 1-37.2 degrees Celsius. These do not need to be manipulated, and the mother bird will adjust the incubation temperature well.
