How can I melt the wild eggs by myself?
1. Egg selection of wild eggs: eggs should meet the variety requirements. Eggs should be small, moderate in size, normal in shape, uniform in shell thickness and bright in color. It is best to store for a short time, because the longer the storage time, the lower the hatching rate.

Second, disinfection: the disinfection of breeding eggs is very important, and the disinfected breeding eggs can obviously improve the hatching rate compared with the unsterilized breeding eggs. Generally, the method of formaldehyde gas fumigation is used to disinfect the eggs. Potassium permanganate 15g and Fokerman 30ml per cubic meter of space fumigated at 27℃ ~ 30℃ for 20 minutes can kill pathogenic microorganisms, especially viruses and mycoplasma. Disinfection is generally carried out in a sealed disinfection cabinet.

3. Temperature: Temperature is the primary condition for incubation. Only at a proper temperature can embryos undergo normal material metabolism and growth and development. The temperature in the incubation period should be relatively stable, and the allowable range is 0.5℃. The temperature of the incubation site should be uniform, otherwise it is difficult to hatch good results. According to the embryo development, the incubation temperature is high in the early stage, gentle in the middle stage, slightly lower in the late stage and slightly higher in the incubation period. The temperature is as follows: preheat the eggs for 6-8 hours before hatching, and the egg temperature is 36℃-38℃; 1 ~ 7 days, 38.8℃ ~ 39.2℃, 8 ~ 14 days, 38.5℃ ~ 38.8℃, 15 ~ 20 days, 38℃ ~ 38.5℃ and 21~.

Humidity: Humidity is also an important condition for the incubation period of mountain eggs. If the humidity is insufficient, it will cause the embryo to stick to the shell, and it will be difficult to hatch or the hatched chicken will be light in weight, and the scales of chicken feet will be rough and dry. If the humidity is too high, the hatched chicken will be heavier, but the egg yolk absorption of the chicken is poor, the abdomen is large, the physique is poor, and it is easy to die, which leads to the decline of survival rate. During the incubation period, the humidity of mountain eggs should be high at both ends and flat in the middle. The high humidity in the early stage can make the eggs evenly heated in the middle stage, which is beneficial to the metabolism of embryos. In the later stage of incubation, humidity is increased to dissipate excessive physiological heat, which makes the eggshell structure loose and convenient for pecking and hatching. The humidity is 60% ~ 65% in the early stage, 55% ~ 60% in the middle stage and 60% in the late stage.

5. Egg-turning: Egg-turning can promote embryo activity, prevent the contents from attaching to the eggshell, and make the incubation period heated evenly. Practice has proved that 1 ~ 20 days, the eggs are turned every 8 hours, and the turning angle is 180 degrees. The development requirements of embryonic eggs can be met without turning eggs during the incubation period of 2 1 ~ 24 days, and the hatching effect is very ideal.

6. Dried egg: In the middle and late period of incubation, the temperature of the egg can reach 38.8℃, and the surface area of the eggshell is relatively small, with small pores and slow heat dissipation. During this period, egg drying can strengthen the gas exchange of embryos and eliminate the accumulated heat in eggs. After hatching 16 days, the eggs should be dried once a day for 20 ~ 24 days, with more physiological calories, twice a day, and the time of drying eggs depends on the situation.

Seven, spraying water: spraying water is one of the keys to improve the hatching rate. Water spraying has three functions, one is to destroy the membrane on the eggshell, the other is to promote the contraction and expansion of eggshell and shell membrane respectively, destroy their integrity, increase permeability, accelerate the evaporation of water and the normal weightlessness of eggs, make the air chamber bigger and provide sufficient oxygen, and the third is to make the eggshell brittle. When the shell thickness of mountain eggs is reduced to 35℃, the eggs will continue to hatch. The shell is hard, the former affects the evaporation of gas and water, and the latter hinders the pecking of the shell. The existence of membrane on the shell is beneficial to the first few days of incubation. With the continuous increase of embryo age, especially when the allantois is closed, more oxygen needs to be inhaled and a large number of metabolites are discharged, which will have an adverse effect on embryo development. Therefore, it is necessary to spray 3 1 ~ 38 on 24-day embryos. Under the action of repeated water spraying on dried eggs, eggshells become brittle from hard, and chicks are easy to break their shells, reducing the stillbirth in the early stage.
