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. 1. Chicken: The incubation period is 21 days. 1 to 6 days is 39.5°C; 7 to 14 days are 38°C; 15 days are 39°C; and 16 to 21 days are 38 to 39°C. 2. Duck: The incubation period is 28 days. From 1 to 7 days, 39°C; 8 to 16 days, 38.5°C; 17 days, 38°C; and 18 to 28 days, 37.5°C. 3. Geese: The incubation period is 30 days. 1 to 8 days is 39°C; 9 to 18 days are 38°C; 19 days are 38.5°C; and 20 to 30 days are 37.5°C to 38°C. 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. 1. In the initial stage of incubation, the relative humidity should be maintained at 60% to 70%. 2. In the middle and later periods, the relative humidity should be maintained at 50% to 55%. 3, the shell needs to maintain the relative humidity of 65% to 70%.
