Generally speaking, the hatching time of chicks does not need 27 days, but only needs about 2 1 day (the hatching time may be advanced or delayed 1-2 days due to factors such as the location of eggs). During the hatching of chicks, the temperature on 1-6 was about 38.5℃, on 7- 14 was 38℃, on 15 was 37.9℃, and on16-2/kloc-0 was 37.3-37℃.

1. Are there any chickens that have been hatched for 27 days?

1. Under normal circumstances, no chicks hatch within 27 days.

2. Under normal circumstances, it takes about 265,438+0 days for chicks to hatch, but the hatching time may be advanced or delayed by 65,438+0-2 days due to the location of eggs. During incubation, the incubation temperatures are 1-6 days at 38.5℃, 7- 14 days at 38℃, 15 days at 37.9℃, 16-2 1 day at 37.3-37.5℃.

3. It takes about 28 days for ducks to hatch, including incubation temperature 1-7 days at 38℃, 8- 16 days at 37.8℃, 17 days at 37.5℃ and 18-28 days at 37.3℃.

4. It takes about 30 days for geese to hatch, including 37.9℃ on 1-8, 37.8℃ on 9- 18, 37.8℃ on 19, and 37-37.3℃ on 20-30.

Second, how to manage the chicks after they hatch.

1, drinking water

(1) Chickens should drink water for the first time within 24 hours after hatching (the first drinking should be done before eating).

(2) When drinking for the first time, it is appropriate to use sugar boiled water or warm boiled water at about 65438 08℃, which can promote the digestion and absorption of egg yolk by chicks.

(3) Gentamicin can be added to drinking water (80,000 units per 0.5kg of drinking water) to prevent diseases.

2. Open food

(1) Chickens start feeding about 12-24 hours after hatching.

(2) It is advisable to use the mixture of wet corn flour and small broken rice as the starting material, and spread the starting material on a plastic cloth for chicks to eat freely. Then gradually switch to the feeding trough for feeding.

3. Temperature and humidity

(1) When it comes out of the shell, the ambient temperature is controlled at about 32-35℃, and then the temperature is reduced by about 2℃ every 7 days. If the chicks are crowded near the heat source and their feathers are unkempt, it means that the temperature is too low. If the chicks stay away from the heat source, open their mouths to breathe and drink plenty of water, it means that the temperature is too high.

(2) Before the age of10, the ambient humidity should be controlled at about 60-65%. After 10 days old, the ambient humidity is controlled at about 50-60%.

4. Lighting equipment

65438 years old +0-3 days, keep the light for 23-24 hours every day. 4-5 days old, keep the light for 20-22 hours every day. 6-9 days old, keep the light duration 16- 18 hours every day. 10- 14 years old, keep 14- 16 hours of light every day. 15-28 days old, keep 12- 14 hours of light every day. 28-42 days old, keep 8- 10 hours of light every day.
