Generally, it takes about 2 1 day to hatch chicks with eggs, and 18 days to set the eggs and 7 days to shine them. Generally, it is affected by room temperature, which may lead to early or delayed hatching. Natural hatching, with hens hatching eggs, can save labor and provide suitable temperature and humidity, but it is not suitable for large-scale hatching of eggs, and suitable temperature and humidity control can directly affect the hatching rate of eggs.

Matters needing attention for hens to hatch chicks

1, Hatching place: Hens don't move their places when hatching chicks, and they are easily threatened by animals such as rats, weasels and snakes. It is necessary to find a safe hatching place for hens. You can put them in a big cage, and then put the chicken cage in a higher place in the henhouse, and keep the environment quiet so as not to disturb the hens.

2. Food and drinking water: Before the hens hatch their chicks, they need to be provided with enough food. Feed made of millet, wheat, sorghum, corn, bean cakes and other foods can be prepared, and fish meal and bone meal can be added to the feed. In addition, to provide enough drinking water for the hens, an automatic water dispenser can be used to replenish water.

3. Appropriate temperature: When hens hatch chicks, if the ambient temperature is too high, the embryos will die and the eggs will be rotten, while if the ambient temperature is too low, the embryos will not develop. It is best to control the temperature of the henhouse at 35-40 degrees to improve the success rate of hatching, and open the window at noon to ventilate the room.

4. Feeding method: When feeding hens, it is necessary to install lighting on the henhouse, so that the hens can receive12-14 hours of light every day, and after the chicks hatch successfully, they need to be transferred to the brooding room with a stable temperature of about 32 degrees, and food such as cooked millet and broken corn should be provided to the chicks.
