First, incubator preparation
1. Incubation room: Choose a house that is dry and conducive to keeping warm and cold, depending on the size of the incubation.
2, hatching bed: placed in the hatchery. It is 2 meters long and 1 meter wide, surrounded by 18 centimeters high planks or fences. According to the hatching scale, single-layer or multi-layer beds can be used.
3, hot water bags: commercially available double agricultural plastic film can be made, its width is often 1 meter, each hatching bed is about 4 meters long. The long side of the film bag is sealed, and the wide sides of the bag are sealed with a roll-fold method so that the opening can be replaced with cold and hot water.
4, thermometer: Each bed with red liquid thermometer 3-4.
5. Insulation products: Each bed requires 3-4 kilograms of 1 batting, 1 cotton blanket, and 2 meters of a white mat cloth about 1 meter wide.
Second, hatching operation method
1. Putting eggs on the bed: Put a layer of 10-15 cm thick old cotton wool or hay on the bed as the bottom insulation layer, then spread an old newspaper, place the water bag flat on the bed, and stuff it with cotton wool to facilitate the insulation. Then inject a suitable amount of hot water at 40°C into the water bag and swell the water bag to a height of 12-15 cm. A layer of white cloth is placed on the surface of the bag, and the hatching eggs can be tiled one by one. The thermometer is placed under the eggs in the center of the bed and at both ends, and the batting and the cotton blanket are overlaid on the eggs.
2, the temperature control: mainly by changing to the water bag to add hot water and cover cotton tires, cotton blankets to adjust the thickness. Generally, the thermometer should be observed once every 3-4 hours, and the temperature can be adjusted in time.
3, normal turning eggs: 12 hours after hatching began to turn the egg until the hatching, every 3-4 hours combined with observation of temperature should turn the egg once.
4, moderate airing: generally 7-10 days after hatching eggs, in winter and spring once a day. Eggs are regularly dried every day, and the cover is uncovered. When the egg temperature drops to about 33-35°C, the cover is gradually returned to its original temperature.
