How to hatch chickens artificially

1. Select the eggs to hatch. First of all, we should pay attention to the source of breeding eggs, and breed eggs with high yield, high quality and disease-free; Secondly, we should choose eggs with clean surface, oval shape, egg weight of 50-60 grams, uniform shell thickness, positive color and no damage.

2. The storage time of eggs should not exceed 3 days at the temperature of 65438 00℃-65438 05℃. The longer the storage time, the worse the hatching effect. If it is stored at 2 1℃-25℃, it can't exceed 7 days at most.

3. Do a good job in disinfection of eggs. After eggs are produced, they are polluted by feces and dust, and there are a lot of bacteria on the eggshell, which not only affects the hatching of eggs, but also pollutes incubators and utensils and spreads various diseases. Before hatching eggs, they must be disinfected once.

4. Strictly control the incubation temperature. Preheat eggs 12 hours before hatching. The method is to put the eggs in an egg tray with the big head up and preheat them to 22℃-25℃.

Extended data:

If the egg is laid at four o'clock, it will be lit at twelve o'clock in the evening and the egg will be turned over. The next day, the temperature of the eggs on the upper layer is very suitable, but the eggs on the lower layer are hot. At this time, it is necessary to change places, that is, put the eggs on the lower floor, put the eggs on the upper floor, and then cover them with a quilt. Pay attention to the time node and turn the eggs every two hours.

When turning, pay attention to the position of the eggs on the side and in the middle to ensure that all hatched eggs are heated evenly. If the egg feels hot when it is turned, take it out to dry for a while and let it cool down. When the shell is about to burst, the quilt can be removed, which can ensure that the embryo can get fresh air. ?
