Temperature and humidity conditions during poultry hatching

First, temperature conditions Temperature is the primary condition for the development of poultry embryos. Poultry embryo development at different times, the requirements for temperature conditions are basically the same.
Chicken: The incubation period is 21 days. From 1 to 6 days it is 38.5°C; from 7 to 14 days it is 38°C; from 15 days it is 37.9°C; from 16 to 21 days it is 37.3 to 37.5°C.
Duck: The incubation period is 28 days. 1 to 7 days are 38°C; 8 to 16 days are 37.8°C; 17 days are 37.5°C; and 18 to 28 days are 37.3°C.
Geese: The incubation period is 30 days. It is 37.9°C for 1 to 8 days, 37.8°C for 9 to 18 days, 37.8°C for 19 days, and 37.0°C to 37.3°C for 20 to 30 days.
Second, the humidity condition The humidity condition is the basic guarantee that the poultry maintains the embryonic development. The relative humidity requirements of poultry during different incubation periods are basically the same.
In the initial stage of incubation, the relative humidity is required to be maintained at 60% to 70%; in the middle and later periods, the relative humidity is required to be maintained at 50% to 55%; during the shelling period, the relative humidity should be maintained at 65% to 70%.
