How many days do eggs hatch chicks? How many days does it take for the eggs to hatch out of the chic

It takes about 21 days for a hen to hatch a chick, because hatching chicks requires a warmer environment, resulting in a hen may not be successful when hatching chicks, experienced hens hatch chicks with a higher success rate, some young hens because they are inexperienced, the hatching rate is lower or a chick can not hatch.

The time it takes for eggs to hatch chicks also varies depending on the temperature, and if the temperature is higher, the eggs can hatch in as little as 19 days. Because of the high temperature, the embryo develops.

Fast, but the hatched chicks may be weaker.

Generally, the chicks will all hatch in 21 days, at this time we can prepare water and food, it is best to put it next to the nest, so that the chicks and hens can eat, and we should also pay attention to frequent checks and add food in time.

How many days does it take to hatch chicks.

It generally takes 21 days to hatch chicks, 18 days to put on the plate, 7 days to shine on the eggs, affected by temperature, there may be early or delayed hatching of chicks.

Chick hatching process for 1-21 days.

1. Chick incubation for 1-4 days is the stage of internal organ development and formation.

2. Chick incubation for 5-14 days is the stage of development and formation of external organs.

3. Chick incubation for 15-19 days is the stage of embryonic growth.

4. Chick hatching for 20-21 days is the stage of chick hatching.

5. The temperature of the chicks should be kept within 1-18 days of incubation, and the relative humidity should be kept at 40%-60%; The temperature should be maintained at 19-21 days of incubation and the relative humidity should be maintained at 65%-75%.

6. During the development of the embryo, it is necessary to continuously inhale oxygen and discharge carbon dioxide and water, and pay attention to timely ventilation.

The incubation of chickens generally takes 21 days, and when hatching chicks, it is necessary to ensure that the environment is warm enough, otherwise it will be difficult to hatch the chicks. During incubation, the ambient temperature needs to be controlled and not higher than the maximum temperature, which takes 21 days. If the temperature is a little higher, it may be two days earlier, and if the temperature is low, it will take 21 days.

Whether it is artificial incubation or hen incubation, the incubation temperature of eggs is required to be about 21 degrees Celsius, from hatching to chick out of the shell normally takes 21 days, but it will also change with the outside temperature, if the temperature is higher can be less than 19 days, if the temperature is low, it will take 21 days.

It takes about 21 days for the eggs to hatch <> the chicks, which may be earlier or later depending on room temperature. The 1st to 4th days of incubation belong to the internal organ development stage, 5-14 days belong to the external organ formation stage, 15-19 days belong to the embryonic growth stage, and 20-21 days belong to the shelling stage (generally 20 days to start hatching, a large number of hatchers in the day, 21 days to hatch all the hatching).

1. How many days does it take for eggs to hatch chicks

1. Regardless of artificial incubation or hen incubation, it usually takes 21 days for eggs to hatch chicks, which may be affected by room temperature, and may hatch early or late. At 19 days of incubation, the chicks usually start to peck at the shell, hatch at 20 days, hatch in large numbers, and hatch all at 21 days.

2. The 1st-4th day of incubation belongs to the internal organ development stage, the 5-14 days belong to the external organ formation stage, the 15-19 days are the embryonic growth stage, and the 20-21 days are the shelling stage. During this period, it is necessary to control the temperature and humidity, do a good job of ventilation and egg turning, etc., to improve the hatching rate.

3. Chick incubation is divided into natural incubation and artificial incubation: natural incubation is not suitable for large-scale incubation of eggs, but it can save labor and provide suitable temperature and humidity; Artificial incubation increases the hatchability of eggs.

2. Temperature and humidity requirements for hatching chicks

1. Temperature. 1) Master the heating principle of "high in the front, flat in the middle, and low in the back", and the temperature can be controlled on the 1st to 6th days of incubation; On the 7th-14th day, the temperature can be controlled at 38; On the 15th day, the temperature can be controlled; On days 16-21, the temperature can be controlled. The specific temperature is influenced by factors such as egg size, breed and ambient temperature, as well as machine performance.

2) High or low temperature will affect the development of embryos, only the appropriate temperature required for the normal development of embryos can obtain a higher hatching rate and hatching rate.

2. Humidity. 1) When incubating in batches, the humidity should grasp the principle of "high at both ends and low in the middle", and the relative humidity at the early stage of incubation (1st-7th day).

It is advisable to keep it at 60-70%; In the middle and late stages of incubation (8-16 days), it is advisable to keep the relative humidity at 50-55%; During the hatching period (after the 17th day of incubation), the relative humidity should be kept at 65-70%.

2) Whether the incubation humidity is suitable can be measured by a wet and dry bulb thermometer, or it can be judged according to the size of the egg air chamber, the amount of weight loss and the peck of the hatch.

Chick incubation is divided into natural incubation and artificial incubation.

The incubation period of chickens is about 21 days, 18 days of putting on the plate, 7 days of eggs, generally to room temperature, there may be early or delayed hatching.

Natural incubation, with hens hatching eggs, can save labor and provide the right temperature and humidity, but is not suitable for large-scale incubation of eggs.

Proper temperature and humidity control can have a direct impact on egg hatchability.

Therefore, the hatchability of eggs can be improved by choosing the appropriate incubation technology and manually controlling the incubation environment.

Under normal circumstances, the incubation time of the chicken is 21 days, sometimes the reputation rent will be a few or more than ten hours, this is because of the different temperatures given, has been incubated for 20 days, the temperature at this time can not be high, about 37 degrees, with a small flashlight, to see if there is a black shadow inside, whether there is a chicken mouth in the air cong room, and it is moving, if it can move, it is alive.

Chicken eggs throughout the incubation period, to be certified to operate and manage, but according to the characteristics of embryonic development, there are two key periods, 1 day embryo age 7 days embryo age and 18 days embryo age 21 days embryo age.

In the incubation operation, as far as possible to create incubation conditions suitable for the development of embryos at these two stages, that is, to grasp the main contradiction between improving hatchability and chick quality.

Generally, attention is paid to heat preservation in the early stage and ventilation in the later stage.

The development of the chicken embryo outside the mother mainly depends on the external conditions, i.e. temperature, humidity, ventilation, egg transfer, etc.

High temperature affects the rapid development of embryos, the shortening of the incubation period, and the increase of embryonic mortality under high temperatures.

Low temperature affects the stunted development of embryos under low temperatures, prolongs the incubation period, and increases mortality.

Therefore, the temperature to ensure the normal development of the embryo is between 35 and 35 degrees.

About two weeks at the earliest. Or 21 days, about half a month Remember not to drink too late to drink, eating will cause excessive hunger and lack of water in the chicks, generally should be provided within 24 hours after the hatch of the drinker, can be placed under the brooder. Let the chicks drink freely.

When eating, you can sprinkle corn flour or fine-grained flour or fine-grained flour feed on paper or wood with something to gently chant and train chicks to peck. A few days ago, the temperature of drinking water for chicks was controlled at 18 21, and the chicks refused to drink more than 30 warm water after coming out of the shell. Be sure to drink before eating.

In some places, in order to prevent diseases and enhance the vitality of chickens, the chicks were given low-concentration brown sugar water or potassium permanganate solution a few days ago. You can search the Internet for chick management methods.

It takes 21 days for eggs to hatch into chicks, and when the incubation temperature is at a temperature of incubation, hatching days are hatched; Time is the day; 21 days; When the temperature is high, the embryo develops quickly, but the chicks are weak. The optimal temperature range for the development of the chicken embryo is between.
