Place a layer of waste paper on the

Place a layer of waste paper on the bed, then even a layer of white paper (clean old newspaper or cement paper). Place a plastic bag with the film on the bed, put the plastic bag around the bed as an insulating layer around the cotton wool and cloth, and pour 40°C warm water into the film cover. Each bag with a film bed is filled with 8-10 barrels of warm water. That is, a bag with hot water with a height of 12-15 cm is formed. At this point, apply another layer of white cloth to the surface of the bag (which can be replaced and cleaned at any time). And finally the hatched eggs can be arranged in rows from the top. Usually, you can have about 300 goose eggs in each bed. After spawning, place a thermometer in the middle of the bed and below the egg surface at each end. You can measure the temperature of the egg at any time. Cover the surface of the egg with a cotton hoop and a blanket. Do not expose the eggs.
