First, choose to plant eggs before hatching. Eggs are better within a week, preferably within 3-4 days. The temperature is controlled at 37. 1 ~ 37.2℃ and the humidity is controlled at 70 ~ 80%.

2. Move the hatched eggs from the hatched egg tray to the hatchling tray by hand. During the operation, the room temperature should be kept at about 25℃, and the action should be fast. The eggs of each incubator should be completed in 30 ~ 40 minutes, which is too long for embryo development.

3. When the chickens hatch to 20.5 days, a large number of chicks are hatched, and the whole batch of hatched chicks can be liquidated as long as they are picked up twice; If the eggs are hatched in batches, they should be picked every 4-6 hours because the chicks are uneven. During operation, chicks with malabsorption of umbilical cord and dry villi should be temporarily left outside the chick machine. The temperature of the incubator was raised by 0.5 ~ 65438 0℃, and after 265438 0.5 days, the chickens hatched into weak chicks.

4. Chickens are immunized with Marek's vaccine within 24 hours after hatching and transported to the brooding house in the shortest time.

1. Natural hatching with hens can save labor and provide suitable temperature and humidity, but it is not suitable for large-scale hatching of eggs.

2. Proper temperature and humidity control can directly affect the hatching rate of eggs. Therefore, choosing suitable hatching technology and manually controlling the hatching environment can improve the hatching rate of breeding eggs.
