The details are as follows:

1. Low fertilization rate

Under normal circumstances, one rooster is usually paired with eight hens, which can not only increase the rooster's desire , and can satisfy the hen's super high fertilization rate. The question asked, only 2 chicks hatched from 7 eggs. The possible reason is that there are fewer roosters around the house, but it doesn't matter. In order to increase the hatching rate, it is very easy to select fertilized eggs for the hens. If necessary, what we rural people usually do is take the eggs of the last 20 days and shine them under the light. If there is a small black mark, it is fertilized. The other eggs are commonly known as "little eggs". Little eggs mean that they cannot hatch chicks. of.

2. Eggs stored for too long

The eggs to be hatched cannot be eggs that have been stored for too long. They are usually fresh eggs within 20 days. Choose eggs that are evenly shaped and fertilized. If you can't tell which eggs are older than 20 days, you can shake the eggs with your hands. If you can feel the shaking inside the eggs, don't discard them. We rural people call these "wake eggs", and the eggs will not hatch.

3. Eggs do not "tread water"

Under normal circumstances, the time it takes for rural hens to hatch eggs by themselves is usually 20 days, so remember the time when incubation starts, and before hatching For one or two days, usually the 18th and 19th days, you need to put the hatched eggs in warm water (approximately 40° water based on the hand touch), and tread water on the eggs. At this time, the chicks are ready to hatch. It will move around on its own. After moving a few times, it can be put back into the chicken coop. If this step is not done, many chicks will not peck open the egg shells and suffocate inside.

4. Temperature changes greatly

When hatching chicks, the temperature of the chicken coop environment must be suitable. It should not be exposed to wind, rain, or sunlight. Pay attention to the ventilation of the chicken coop in case of sudden changes in weather. You need to pay attention to the cooling and heating conditions of the chicken coop. It should not be too cold or too hot. It sounds complicated, but it is not difficult. On hot days, cover the chicken coop with a piece of cloth to keep the chicken coop ventilated. In order to prevent sudden drops in the weather, Before hatching, add some straw to the chicken's nest to make it resemble a bird's nest. The few straws in the title picture are too few.
