Duck Egg Hatching: Mixed Bed Hatching

All kinds of traditional incubation methods will be transferred to the last stage after the incubation. The basic operations are described as follows:
1. Temperature adjustment measures The work of adjusting the temperature after being shared is the center of management work. The specific measures are as follows:
(1) Turning eggs (grab stalls) Turn the eggs in the stall and swap the position of the eggs and eggs. Because the eggs are easy to dissipate, and the temperature of the eggs is low, the eggs in the middle of the bed are not easy to dissipate, and the temperature of the eggs is easy to rise. By changing the position, the egg temperature can be balanced and even.
(2) Adjust the egg density Adjust the egg temperature by adjusting the number of layers and the elasticity of the eggs. When they are on the booth, they can be placed in double layers and arranged closely. As the embryonic eggs rise from the temperature, the upper layer can be put more thinly. Later, as long as the eggs are placed on the double layer, then all are laid flat.
(3) The increase or decrease of the cover is adjusted by the increase or decrease of the quilt, the single bedding, etc., and the flip cover. When the temperature of the egg is low, the cover can be covered; if the temperature of the egg rises faster, the cover can be reduced, and even the cover can be lifted to hang the egg.
(4) The opening doors and windows, windows and windows are also auxiliary facilities for regulating egg temperature. In the early stages and in the cold season, doors and windows should be closed to facilitate heat preservation; in the later period of rapid heating or high temperatures in summer, doors and windows should be opened to increase ventilation to facilitate heat dissipation.
2. Principles of temperature adjustment and precautions The adjustment of the temperature of the shared bed should be based on the characteristics of temperature difference between the heart and the side of the egg. It is necessary to grasp the principle of “mainly stabilizing, stabilizing and stabilizing, and stabilizingâ€. That is to say, in order to make the egg temperature tend to be consistent, it is necessary to maintain the balance of the proper temperature of the heart and the egg; but when the heart is kept at a moderate temperature, the temperature of the edge egg must be low, which is to be exchanged between the egg and the egg. The location and proper stamping are used to warm up the temperature to make up for the lack of temperature; when the temperature is up to the required level, control measures must be taken in due course so that the temperature will not rise too high.
The hatching hatch should pay attention to "three look." A look at the embryonic age. With the growth of the embryonic age, its spontaneous temperature is increasing, coverings should be from more to less, from thick to thin, covering the time from long to short. Second, look at the temperature and room temperature. In winter and early spring, the temperature and the room temperature are relatively low. It is necessary to cover more properly and the cover time should be longer. In summer, the temperature is high, cover less, and the cover time should be shorter. Three times to see the cover and egg temperature. According to the egg temperature level or moderate to different conditions, timely increase or decrease the cover, as above, once the temperature rises fast, rises high, then the next time will cover a little; as a result, the temperature rises slowly, the temperature is low, then the next time It is necessary to cover a little more; if the temperature is suitable for the next time, it will remain as it is.
