What conditions are needed for chicks to hatch?

Appropriate temperature and humidity are needed, and ventilation is also emphasized.

Appropriate temperature: the temperature is controlled at 37.1 to 37.2 degrees Celsius.

Appropriate humidity: Humidity is controlled at 70 to 80%.

Chick hatching is divided into natural hatching and artificial hatching.

Chickens incubation period of about 21 days, 18 days to fall plate, 7 days to shine eggs, generally to the room temperature effects, there may be early or delayed hatching.

Choose a paper box or wooden box incubator to hatch chicks, about thirty to sixty eggs can be hatched at a time, this method is simple and easy to do, you can easily realize hatching in your own home.

The specific method of hatching is: according to the number of eggs hatching small incubator choose the appropriate paper box or wooden box, to the bottom of the box and around the paper paste tightly, the bottom of the box can be laid on the cotton and so on.

Put the selected high-quality eggs into the box, generally not more than three layers, put a thermometer on top of the eggs, the top of the box should be covered tightly with a quilt, so that the temperature inside the box to maintain about thirty-eight or nine degrees, and at the same time every six hours or so do a good job of turning over the eggs in order to maintain an even temperature.

The four points of chicken hatching

Breeding egg preheating into hatching

The air-conditioned egg bank in the breeding eggs to 22 ℃ ~ 25 ℃ indoor preheating for 6 to 8 hours, remove the egg surface vapor, to be the surface temperature of the egg to reach the room temperature that is the yards of the plate into the hatching.

Temperature control

Temperature is the primary condition for chicken embryo development, incubation temperature control should be smooth, to prevent sudden high and low. Chickens incubate for 21 days: 1 to 6 days incubation temperature of 38.5 ℃, 7 to 14 days of 38 ℃, 15 to 18 days of 37.8 ℃, 19 to 21 days of about 37.4 ℃.

Control of humidity

Control of humidity, in the early stage can make the embryo heat evenly, in the middle and late stage is conducive to heat dissipation and pecking shell out of the chick. In general, relative humidity: 60% to 70% for 1 to 7 days, 50% to 55% for 8 to 16 days, and 65% to 70% after 17 days.

Ventilation

Chicken embryo development must constantly exchange gas with the outside world, especially in the late incubation period, the embryo began lung respiration, oxygen demand increases, carbon dioxide discharges increase, this time should increase the ventilation to keep the air fresh.
