Chickens bought at home in rural areas are easy to die. How do you spend the safety period?

It is very difficult to feed 100% of the chicks that have just hatched out of the shell bought by village families from small vendors. Is there any way to improve the survival rate of chicks and let them grow normally and healthily.
This method, of course, can make the newly hatched chicks grow and develop normally and reach a very high survival rate. Why is the chick just out of the shell very weak, very delicate and easy to die?
In the past, chicks in rural families were hatched by their own hens. The temperature for hens to hatch chicks is 37.5 ℃. After 21 days, chicks will break out of their shells. The chicks that have just hatched are very weak. When the temperature of the natural environment is lower than 30 ℃, the chicks can't resist such low temperature. Therefore, they tend to die from low temperature.
When the temperature is too low, the hen will use its warm body to hug each chick and shield the chick from the cold until the chick recovers its normal function.
Therefore, the chicks hatched by hens are under the meticulous care of hens. Once the temperature drops, the chicks will be automatically insulated and warmed, so that the chicks can survive the frail period of one month safely and normally and healthily.
Therefore, rural families now buy chicks from small vendors, which are hatched by chicken farms using incubators. Such chicks must be protected artificially. They can live normally in a suitable temperature environment, safely pass the safety period of one month, and can survive normally and healthily.
The chicks just bought by farmers are kept warm in two ways. The first is to keep the ground warm and the second is to keep the space warm. As long as this way of keeping warm and warm, you can control the good living space of the chick and live normally and healthily.
The way to keep the chicken warm on the ground is to get the chicken out of the cold soil and use a cardboard box with an area greater than 3~5 times the area of all the chickens. Because the bottom of the carton isolates the chicken from the cold soil surface, which can improve the surface temperature. In addition, the carton can absorb moisture.
Then lay a layer of dry sawdust on the bottom of the carton, which can not only keep the chicks warm, but also absorb the fecal water discharged by the chicks, so that the chicks can maintain normal temperature, so that the chicks can eat, drink, move and rest in a dry and warm environment.
The use of cartons is conducive to protecting the chicks in the cartons. There is no excessive air flow, and the resulting cooling can prevent the surrounding cold air from entering the cartons, providing good conditions for the chicks to keep warm and cold. In addition, the chicken is maintained in cartons, which is easy to move, flexible and convenient.
When the indoor temperature is lower than 25 ℃ in the daytime, move the chicken to the sun to add warmth to the chicken. If the outdoor temperature is higher than 38 ℃, you can move it indoors. If the temperature is too low at night, the carton can be covered with a layer of thermal insulation, such as foam board, film paper, newspapers, old clothes, etc. In principle, it should be ventilated and warm. In rainy days and low temperatures, we should also keep warm like this. If the temperature is too low, you can also use a heater to warm the chicken.
For chicks to feed and drink, they can use a special feeder and water dispenser. Pay attention to avoid spilling water into the carton. They can use a plastic film mat, and the water dispenser can contain a small amount of water. In this way, after feeding for a month, the chicks gradually grow up and strengthen, and can resist the natural environment, and can be raised in various ways. As long as farmers take good care of them, it is not very difficult to ensure that the survival rate of chickens is 100%.
