Hatching Skills-Part 1

Chapter 1 -Preparation before hatching

1. Prepare an incubator

Prepare an incubator according to the capacity of hatches required. The machine must be sterilized before hatching. The machine is powered on and water is added to test run for 2 hours, the purpose is to check whether there is any malfunction of the machine. Whether the functions such as display, fan, heating, humidification, egg turning, etc. are working properly.

2. Learn the hatching requirements of various types of eggs.

Hatching of chicken eggs

Incubation time about 21 days
Cold egg time start around 14 days
Incubation temperature 38.2°C for 1-2 days, 38°C for the 3rd day, 37.8°C for the 4th day, and 37.5′C for the hatch period on the 18th day
Incubation humidity  1-15 days humidity 50% -60% (to prevent the machine from lock of water), long-term high humidity in the early incubation period will affect development. the last 3 days humidity above 75% but no more than 85%

 

Hatching of duck eggs

Incubation time about 28 days
Cold egg time start around 20 days
Incubation temperature 38.2°C for 1-4 days, 37.8°C from the 4th day, and 37.5°C for the last 3 days of the hatch period
Incubation humidity  1-20 days humidity 50% -60% (to prevent the machine from lock of water,long-term high humidity in the early incubation period will affect development)the last 4 days humidity is above 75% but not more than 90%

 

 Hatching of goose eggs

Incubation time about 30 days
Cold egg time start around 20 days
Incubation temperature 37.8°C for 1-4 days, 37.5°C from 5 days, and 37.2″C for the last 3 days of the hatch period
Incubation humidity  1-9 days humidity 60% 65%,10- 26 days humidity 50% 55% 27-31 days humidity 75% 85%.The Incubation humidity &temperature gradually decreases with the incubation time. but the humidity must gradually.Increase with the incubation time. Humidity softens eggshells and helps them emerge

 

3. Select incubation environment

The machine should be placed in a cool and relatively ventilated place, and prohibited to be placed in the sun. The temperature of the selected incubation environment should not be lower than 15°C and not higher than 30°C.

4. Prepare the fertilized eggs for hatching

It is best to choose 3-7 day old eggs, and the hatching rate will decrease as the egg storage time becomes longer. If the eggs have been transported over long distances, check the eggs for damage as soon as you receive the goods, and then leave them with pointed side down for 24 hours before hatching.

5. Winter needs to “wake up the eggs”

If hatching in winter, in order to avoid excessive temperature difference, the eggs should be placed in the environment of 25 °C for 1-2 days to “wake up the eggs”
