1. Preparation before incubation in order to avoid malfunction during the incubation period. Therefore, carry out comprehensive maintenance work before incubation, check the accuracy of the temperature regulator and thermometer; whether the motor, fan, electric heater, indicator light and alarm device are sensitive, whether the door, four walls and floor of the incubator are tight, and whether the egg tray is tight. Check whether the hatching tray is firm or not. Prepare the generator for use in the event of a power failure.
After sterilizing the incubator and testing the machine for 24 hours, everything is normal before the hatching eggs can be hatched. The hatching eggs from the egg storage are placed in an incubation room at about 22 degrees Celsius for 4-6 hours, and the eggs are placed on a plate with the big end up and sterilized.

2. Incubator management Modern three-dimensional incubators are highly mechanized and automated. Therefore, management is relatively simplified, but the amount of incubation is large. Once an accident occurs, it will cause great economic losses. Managers must carefully do the following Management tasks:

(1) Temperature adjustment
Pay attention to the changes in temperature, observe the sensitivity of the regulator, and whether the change of the indicator light of the thermometer is consistent. If the temperature adjustment performance is stable, don’t twist it easily after adjusting the temperature, unless the temperature deviates from ±0.5 degrees Celsius and needs to be adjusted immediately. The temperature is generally recorded every hour.

(2) Humidity adjustment
Modern three-dimensional incubators have automatic humidity control equipment. There is no automatic humidity control incubator. There is a water tray in it. Water should be added to the water tray regularly every day. If the humidity is too high, reduce the water tray, or increase the water tray or adjust the water temperature if the humidity is insufficient. The water cup of the wet bulb meter should be filled with water frequently, and the cotton rope should be cleaned and replaced regularly to ensure the accuracy of the wet bulb meter.

(3) Fans and egg racks for ventilation, turning eggs, and other management incubators should be kept clean and dust-free, so as not to affect the ventilation in the incubator.
The three-dimensional incubator can turn the eggs at a fixed angle regularly, generally once every 1-3 hours. When turning the egg by hand, it should be light, steady, and slow to avoid malfunction. The motor should be refueled regularly, and pay attention to whether the machine is running normally and whether there is any abnormal sound. Record the temperature, humidity and room temperature every day.

(4) Egg imaging: Carry out egg imaging on a regular basis to check the development of the embryo. The operation requires light, fast, and accurate movements to prevent shock and damage to the embryo. Observe carefully to avoid missed and wrong photos.

(5) Moving eggs (dropping tray) The embryonic eggs are moved from the incubation tray to the hatching tray, which is commonly referred to as moving eggs and trays (dropping tray). The embryos are moved to the hatching tray on the 18th to 19th day of incubation. The age of the egg transfer depends on the development of the embryonic egg. If the embryonic development is retarded, the transfer of the egg can be delayed for 12-24 hours. When embryo eggs are moved into the hatcher tray, place them flat and stop turning the eggs.

(6) Hatch
Chicken embryos start to hatch in 20 days, turn off the lighting of the hatcher, so as to prevent the chicks from disturbing and affecting the hatching. When the chicks begin to hatch 3-4 hours, when the chicks feathers are dry, the chicks can be picked and the empty eggshells can be picked out at the same time.

(7) After cleaning and incubation, withdraw the hatching tray, hatching tray, water tray, brush off broken eggshells, dirt and fluff, rinse and dry, and then fumigation or disinfection with disinfectant can be used for disinfection. spare.

Only by insisting on the daily maintenance of the incubator can the normal hatching work of poultry be maintained.
