How Many Days Does It Take To Light The Eggs And How To Hatch The Rutin Chickens
Rutin chickens usually start the first egg lighting on the 5th day of hatching, which can be postponed for 1-2 days, but not earlier. Can do the 2nd eggs lighting can be done on the 10th day.
How many days does it take to light the eggs of rutin chickens
Rutin chickens usually start the first egg lighting on the 5th day of hatching, which can be postponed for 1-2 days, but not earlier. Can do the 2nd eggs lighting can be done on the 10th day. The second egg illumination can be done on day 10.
This means that the light source can be used to see how much space the embryos occupy in the egg, and it is convenient to find those eggs that are not developed properly.
In fertilized eggs under the light test, the embryo can be vaguely seen floating, the yolk sac on the vascular network around the expansion of the spider web. And the diffusion surface accounted for 4/5 of the egg body, visible to the original base, and the eye has melanin deposition. The blood vessels were slender in the weakly fertilized eggs. And the expansion surface was small. The diffusion surface was less than 4/5 of the egg body, the embryo body was more petite, and the eye dot was not noticeable. Unfertilized eggs are transparent, sometimes with a faint yolk shadow, blurred air chamber boundaries, and no visible blood vessels or embryos. Dead sperm eggs show bloodlines or blood rings, and sometimes small black dots of sticky shells can be seen.
How to incubate a rutin chicken
Egg hatching method
There are three ways to incubate the eggs of rutin chickens: hen-holding, waterbed incubation, and machine incubation. Due to their own reasons, most rutin hens are unwilling to hold a nest, so they are mainly incubated manually. If you use artificial hatching, you have to prepare the hatching machine.
Seed egg selection
The selection of breeding eggs should be determined according to the seasonal climate. When the temperature is suitable in spring and autumn, breeding eggs within 7 days can be selected. In summer, when the temperature is high, breeding eggs within 3 days can be chosen; in winter, when the climate is cold, breeding eggs within 10 days can be selected.
Wipe the surface stain of the breeding egg with a slightly moist cotton cloth and disinfect it if possible. Put the egg in a container with the big head up and leave it for 6 hours. Then put it into the incubator (the incubator can be disinfected with potassium permanganate) after the condensation on the egg's surface is completely dry.
It takes about 16 days for the breeder eggs to hatch. After the 5th day of incubation, the eggs will be illuminated, and the broken eggs will be removed in time. The temperature is 37.8℃ throughout, or 38.2℃ for days 1-5, 38℃ for days 6-10, 37.8℃ for days 11-15, and 37.5℃ for days 16-19. The humidity requirement is between 50-70%.
To make the eggs evenly heated. The waterbed incubator must be turned manually four times daily, half a turn each. When breaking the shell, the incubator is opened for ventilation for 15 minutes four times a day. When ventilating, you need to spray about 30°C warm water on the eggshells to facilitate the emergence of the shells.
