Is the hatching rate of chicken seedlings too low? Don't just think it's a temperature problem. You may have ignored these

The rate of chicken hatching is high or not, which should be considered.
1、 Control temperature and humidity
Temperature and humidity control is a major part, and the degrees to be mastered at each stage are different.
1. Temperature reference
The incubation temperature is 38 ° for 1-7 days, 37.8 ° for 8-12 days, 37.6 ° for 13-18 days, and 37 ° for 19-21 days. The indoor temperature of the incubator should be controlled between 22 and 26 degrees, so that the incubation effect will be better.
2. Humidity reference
1-7 days is the early stage, the relative humidity is 60%, 8-17 days is the middle stage, the relative humidity is 50%, 18-21 days is the late stage, the relative humidity is 70%. This is because amniotic fluid needs to be produced in the early stage, and urine needs to be removed in the middle stage, which is conducive to shelling in the later stage.
2、 Sprinkle water on the eggshell
Remember to sprinkle water on the eggshell when entering the late incubation stage. While monitoring the humidity every day, spray water on the eggshell. Remember not to use cold water, but warm water. Whether the water is sprayed enough is a key step in the later stage.
When spraying water, be careful not to remove all the covers, which will cause excessive temperature difference in the incubator.
3、 Select widowed eggs
The hatching rate of chicken seedlings is not high, and the fertilization rate should also be considered. On the 3rd and 7th day of entering the incubator, we need to take a picture and select the unfertilized oligo eggs.
4、 Quiet before incubation
If the eggs bought in the incubator or other places come back for hatching, they should be left for 24 hours after being bought, because they are shaken during transportation and cannot be directly put into the incubator to start hatching.
