Light is an important factor that affects egg production. Artificial supplemental light requires attention to the following matters.
The light should be stable. The light time should be short to long, increasing by half an hour per week.
When the light time reaches 16 hours per day, the light should be kept stable, not long or short, and the best way is to supplement light once a day in the morning and once in the evening.
The intensity should be appropriate for normal laying hens, the required light intensity is generally 2.7 watts.
For a multi-layer cage chicken house, the illumination level should be increased to 3.3 to 3.5 watts per square meter in order to have enough illumination on the bottom layer.
Illumination should be evenly installed in the chicken coop light bulbs should be 40 watts ~ 60 watts appropriate, the general height of the lamp 2 meters, lamp distance 3 meters.
If more than two rows of light bulbs are installed in the chicken coop, they should be cross-arranged, and the distance between the light bulbs and the wall should be half of the distance between the light bulbs.
It is appropriate to use red light light color is different, the wavelength varies. Tests have proved that when other conditions are the same, hens kept under red light have a higher egg production rate than laying hens under other colors of light.
