When using battery cage for layers to raise laying hens, we have to give the chicken a suitable growth environment so that the chickens can be raised.
Regardless of the size of the chicken cages for sale or the number of chickens, it is essential to keep the air fresh and well ventilated, especially in high-density chicken houses. The ventilation is not good and there will be a lot of harmful gases such as ammonia and carbon dioxide. The release of hydrogen sulfide and the like affects the normal growth of the chicken, lays eggs and causes various diseases. Therefore, in the production, a floor window should be provided at the bottom of the chicken house, a large window in the middle, and a vented cylinder with a cap on the roof. All open in summer, the central large window can be closed in winter, only the exhaust cylinder of the floor window and the roof can
be left, or the exhaust fan can be set in the middle to quickly eliminate the dirty air in the house. However, the temperature inside the house should not be lowered too low to avoid increasing feed consumption or causing various diseases.
Light has a great influence on the laying performance of chickens. Reasonable light can stimulate ovulation, promote normal growth and development of chickens, and increase egg production. Production should start from the age of 20 weeks, using artificial light to increase the light for half an hour every week until reaching 16 hours a day. Four weeks before the chicken was eliminated, the light time was gradually increased to 17 hours a day until it was eliminated. Artificially supplementing the light works best every morning before dawn. The light intensity is preferably 3 to 5 watts per square meter of ground. The lamp is about 2 meters away from the ground. It is best to install the lampshade to collect light. The distance between the lamp and the lamp is about 3 meters to ensure uniform illumination throughout the house.
The most suitable temperature for feeding chicken hens is 18 ° C ~ 23 ° C, too high or too low temperature is not conducive to laying eggs. In the summer, attention should be paid to the ventilation of the house, and the power of the ventilation fan can be increased. The horizontal ventilation is used for longitudinal tunnel ventilation, so that the wind speed is increased, and the heat generated by the chicken body is taken away in time, such as combining water spray, watering, and appropriately reducing the stocking density. It can reduce the temperature inside the house more effectively. In winter, you should pay attention to warm work. At night or in the wind and snow, the doors and windows
of the chicken house should be covered with straw curtains to improve the temperature. In the north wall of the chicken house, use windshield such as corn stover to keep out the wind, or add rice husks, sawdust, etc. on the top of the ceiling. For the cold layer and so on.
The optimum humidity for the house is 60% to 70%. If the humidity in the house is too low, the laying hens will have feathers and unkempt, dry skin, dull color such as feathers and sputum, claws, and easily cause dehydration of the chicken body, causing respiratory diseases. The thermal conductivity of humid air is 10 times that of dry air. If the humidity in the house is too high in winter, the heat generated by the chicken body will increase, making the chicken colder.
Excessive humidity in the summer house will limit the water released into the air when the chicken breathes, causing the chicken to become contaminated, and the germs will multiply, causing various diseases and causing a decrease in egg production. In the production, it is possible to reduce the humidity in the house by using enhanced ventilation and releasing lime blocks indoors.
Picking eggs in time to create an egg-free environment can increase the egg production rate of chickens. The peak period of laying eggs of chickens is generally 3 to 4 hours after sunrise, and the egg production in the afternoon accounts for 20% to 30% of the egg production in the whole day. In production, eggs should be sorted according to the time of laying eggs and the amount of eggs laid. 2 times, 3 times a day in summer.
