Since the guinea fowl is poor in nesting, the natural hatching method and artificial hatching method of the mother chicken can be used according to the number of hatching eggs. I. Hatching characteristics The incubation period of guinea fowl is 26 days. The mother chicken hatches with 10 to 15 eggs per nest. As individual pearl eggs are small, eggs weigh about 45 grams, and egg yolks account for a large proportion, a high proportion of fat content, coupled with a thick shell, hatching to the middle and late, the embryonic heat production is more difficult to heat outwards, At the end of hatching, it is also difficult for the chicks to break shells. Therefore, incubating pearl eggs according to the hatching method of the chickens results in a lower hatching rate and the chicks hatched are also weaker. Second, hatching technology 1, temperature control: guinea chicken hatching suitable temperature range of 37.5 °C ~ 38.8 °C, hatching temperature of 37.5 °C ~ 37.7 °C. When the summer temperature is high, the internal temperature can drop by 0.5°C. In production, in order to make full use of the incubator and facilitate management, batching and incubating, the temperature of the incubator can be kept constant at 38° C., “new and old eggs†are hatched on the same machine, “new eggs†are placed on the upper layer, and “old eggs†are placed on the lower layer. To make the "new egg" use the excess heat produced by the "old egg" and adjust it once every 3 days, so that an ideal hatching effect can also be achieved. 2, humidity control: Incubation can increase or decrease the water tray in the incubator to change the size of the water to adjust the size of the humidity. Incubation for 1 to 23 days, relative humidity maintained at 55% to 60%, 24 to 26 days, maintained at 70% to 75% is appropriate. To increase the humidity, the role of carbon dioxide in the air promotes the calcium carbonate in the eggshell to change to calcium bicarbonate. The shell becomes brittle, which is good for chicks' shells. 3. Drenching water and airing eggs: Excessive heat generated during the latter half of the embryo development will make the embryo evenly heated and maintain the normal development of the embryo. This is the key to improving the hatching rate. After incubation for 10 days, the egg is drenched with warm water at 38° C. to 40° C. for about 3 to 4 times per day (room temperature is below 25° C., 1 to 3 times per day; room temperature is above 25° C., 4 to 6 times per day). When the water is sprayed, cut off the power supply and pull the egg rack out of the machine. Sprinkle the water with a watering pot or a water scoop. It is advisable to drip the eggshell. Ten days after incubating, dry the eggs together with the water-spraying. After the water is poured, the eggs shall be air-dried to reduce the eggshell temperature to about 32°C. It is advisable to use the eyelids to feel cool and cool. Every day you need to open the hatchery doors and windows 3 to 4 times. After 1 to 7 days after hatching, the vent hole of the incubator was turned off; half of the opening time was 8 to 12 days, and all were opened 13 days later to keep the air inside the machine fresh, and there was enough oxygen for the embryo to develop and exhaust excessive carbon dioxide. After incubating, turn the egg once every 2 hours, turn the egg at an angle of 90 degrees, and stop turning the egg after 23 days. 4, turn eggs hatching: In order to make full use of hatching machine, check the development of embryos, improve hatching rate, after hatching 6 to 7 days according to the first photo, the detection of no eggs and dead eggs; 13 to 14 days in the second, remove Embryos were dying for 23 to 24 days to remove dead fetus eggs. Incubation to 24 days, the egg was transferred to the out of the plate, no turning the eggs, sprayed with 38 to 40 °C warm water every day 3 to 4 times. After hatching for 26 days, chicks were hatched and hatched. Normal hatching was completed 28 days later.
