Generally speaking, it is necessary to ensure the relative humidity, otherwise the young hair will stick to the eggshell and cannot turn around and peck at other positions because of the loss of water. As a result, the eggshell will only peck a small part and stay inside. In addition, if there is a lot of yolk residue, it is necessary to strengthen the egg turning during the incubation process.

Only you know whether your automatic incubator has the function of turning eggs and drying, how to set it up, and whether there is relative humidity control. If you have these functions, you need to set them accordingly. If not, it is basically difficult to control.

disinfect

Before hatching, eggs should be disinfected with potassium permanganate solution. Agricultural companies sell them, and the concentration can be sprayed, bathed or fumigated at low temperature according to the sterilization concentration of farmland.

Turn eggs

Egg yolk is slightly heavier than egg white, so it will sink to the bottom if it is left standing for a long time. If this happens in the process of hatching, it will cause the problem of hatching. In addition to clearing dead eggs in time every time, turning eggs is an important point to improve the hatching rate. Eggs should be turned every half an hour to four hours, and this time is different for different varieties. Generally speaking, small eggs or large egg yolks turn eggs more frequently. The eggs on the incubator are placed at an inclination of 30 to 45 degrees, and turning the eggs is to adjust the inclination to the opposite direction. In this way, during the whole incubation process, the descending line of egg yolk is a broken line, which delays the time for egg yolk to sink into the eggshell.

Chilled eggs

During incubation, the temperature should be strictly controlled within 100F, plus or minus one degree. From 17 days, eggs should be dried every day: the temperature should be reduced to 93F for half an hour. Until the 20th day.

Break away from infancy

On the 2nd1day (the last day), the eggs were moved into the incubation room, and the eggs were moved from the incubation tray to the incubation tray. The temperature increased to 102- 104F, and the relative temperature increased to above 93, so the eggs hatched on their own.

I hope these are helpful to you.
