The laying box should be laid with soft and comfortable, moderate elasticity, clean (sterilized if possible) egg box cushion, such as rice husks, shavings, etc., to ensure that 1/3 of the cushion thickness, but not more than 2/3. If it is too full, it will be difficult for the chicken to enter and turn in the egg box. Do not add new padding to the ground at the beginning of production. Fresh bedding should only be added to the egg box to encourage chickens to use the egg box. After planting eggs, the first contact is the cushion in the box, so it is required to be clean and hygienic. The bedding in the box should be changed as often as possible, and the shavings and rice husks in the box should be changed every 2 weeks. Dried pine shavings are recommended because of their soft texture and natural defense against insects, bacteria and mold. Of course, the effect of potassium permanganate fumigation is better. If possible, the degree of contamination of the bedding material of the egg box should be monitored regularly, and the culture of bacteria, mold and so on should be done. The hen often grasps and oppresses, which will gradually cause the bedding to be thick at the edge, thin in the middle and even see the bottom. In addition to adding it in time, breeders can often pay attention to finishing.Those who use the bottom mat should also pay attention to cleaning, try to use two sets of disinfection in rotation. 

Keep the egg box well ventilated. As mentioned above, the hen's body temperature rises when laying eggs, and direct sunlight (especially iron) should be avoided in summer, otherwise the hens do not want to enjoy the excessive light and high temperature. Many chicken farms reduce the temperature by spray evaporation in summer, so try not to wet the nest of the egg box at this time. Poor ventilation in winter, the humidity of the henhouse bedding material has a great disadvantage, but also to find a way to solve it.
