The success of breeding chicken flocks depends on producing high-quality hatchable eggs and providing high-quality commercial chicks. The average hatching rate of ground eggs is lower than that of normal eggs10%, Moreover, the quality of chicks produced due to environmental pollution is also poor.

The proportion of ground eggs is1%The chicken flock is normal, but if the ground egg ratio reaches5%This indicates that there is a problem that needs to be investigated and studied, and a corrective plan needs to be developed to ensure that the next batch of chickens will not experience it again.

Today, we will discuss how the management of the breeding and laying periods affects the number of ground eggs and how to reduce them.

Incubation period

• The breeding and training of chickens can have a significant impact on ground eggs.

• During the breeding period, using a scaffold to train hens makes it easier for them to enter the egg box. We recommend putting up the scaffolding within the first four weeksfive hundredPut a chicken on a perch. Avoid using electricity to strike breeding chickens on the water and feed lines. Chickens will become nervous and dare not jump onto the trellis in the egg laying coop.

  Raise hens according to the weight standard of the strain. Chickens that are overweight or have too much meat are more likely to produce noodles and eggs.

• Reduce the light intensity during the breeding period to ensure that the light intensity in the egg laying chicken coop reaches seven times that of the breeding chicken coop.

Egg laying period

At the beginning of production, the proportion of ground eggs is, and then it decreases to a normal level. When a hen has already given birth to more than in a certain placefourThey will continue to lay eggs in this place. It is very important to quickly collect the ground eggs at the beginning of laying to prevent the hen from continuing to lay eggs on the ground. After the peak of egg production, it is difficult to further reduce the number of ground eggs.

Egg box management

More and more companies are switching from individual independent egg laying boxes to communal egg laying boxes in order to save labor. Both types of egg laying boxes can work very well. Chickens should

It is easy to enter the egg box to lay eggs, and the egg box should be the place where chickens like to lay eggs. The materials used to make the egg box should be chicken friendly and suitable for the mother

Chickens provide a comfortable environment. It is very important to ensure that there are no areas with air leaks, as hens may not want to use a leaking egg box.
Manual egg laying box

Depending on the type, we recommend morefour point fiveA chicken/Egg laying box. The distance to the egg laying box should be less than 10 meters. The vertical depth of the egg box should be at least 15 centimeters

Rice and provide sufficient padding to reach 2/3 full capacity of the egg box. Okay, there's a strip area that allows the hens to directly enter the egg box area, especially the second layer

The egg laying box. The height of jumping into the egg box is 45 centimeters. Regularly collect eggs every day to avoid having more than three eggs in the egg box; Too many eggs in the egg box will

Increase the risk of damage and premature hatching of eggs.

Automatic egg laying box

Chickens like to lay eggs in the dark, so it is very important to place a curtain at the door of the egg box. In order to attract chickens to the egg box, the strip area should occupy the entire area

40% of the ground area should have slats7%The slope. Place a feeding line and a water line on the board with a spacing of 60 centimeters between them, and a spacing between the feeding line and the egg box

70 centimeters. Never place all the feeding lines on the trellis, as this will prevent the chickens from going to the stocking area and reduce the interaction between the hen and rooster. Turn on the lights

I previously opened the chicken coop and turned off the lights one hour before turning them off.

No matter which type of egg box your farm uses, keep the egg boxCleanliness is the key to providing high-quality chicken chicks.

illumination
The arrangement of lighting should be uniform to avoid shadows that may cause hens to lay eggs. The lighting intensity on the ground should be at least 60 lux, and avoid strong light at the entrance of the chicken coop.

Feeding
Raise the feeding line to allow chickens to migrate freely in the ground area, at least 20 centimeters away from the bedding height. If possible, raise the feeding line after feeding is complete. Start feeding from 30 minutes after turning on the lights or when 80% of the eggs have been laid.

Administration

At least two weeks before laying eggs, transfer the breeding hens to the egg laying coopitThey can adapt to the environment.

• Open the chicken coop when laying eggs. Don't open the chicken coop too quickly, as the hen will lose interest and turn the egg box into a resting place, dirtying the coop.

• The waterline should have a water flow of 80-100 milliliters per minute to meet the drinking water needs of the breeder chickens, without sealing the inlet area of the egg laying box.

• The development of roosters and hens should be synchronized. A lively rooster can drive the hen onto the trellis, but a fierce rooster can cause damage and death to the hen.

• adequateEgg laying boxIt is important.Chickens do not like to wait when laying eggs.The requirement for an automatic egg laying box is to reduce the size of each hen by 100 square centimeters (1 square meter per 100 hens).

• In the first few weeks of production, the proportion of ground eggs is. During the period from the start of laying to the peak of egg production, quickly collect the ground eggs.

• Control weight to ensure that you are not overweight or have excessive muscle mass. Too many overweight chickens cause inconvenience in movement and produce more ground eggs.

• Avoid padding the ground area too deeply -2 to 3 centimeters is sufficient.

• Diseases such as red mites and leg diseases can increase the number of eggs on the ground.
