(I) Feeding and management of chicks 1. Start eating at a proper time. The chicks can be eaten within 12-24 hours of hatching, and within the first 3 days, feed the soaked minced rice or chicken feed. The broken rice or chicken feed is sprinkled on a plastic sheet and the chicks are fed. From the fifth day onwards, an appropriate amount of green feed can be added to allow the chicken to feed freely. Feed 6--8 times a day at 3 weeks of age, 4-6 times a day after 3 weeks of age, and give clean drinking water. You can also add 0.1% potassium permanganate to any of your drinking water. 2. Control temperature and humidity. The required temperature for chicks is 30--31°C in one week of age, 25--30°C in 2--3 weeks old, 20--25°C after four weeks of age, and 55%--65% of indoor relative humidity. It is appropriate. And also maintain ventilation. 3. Maintain the density. The suitable density for laying chickens per square meter is: 40--50 within 10 days, 40 within 20 days, 30 within 30 days, and 10--12 days after 90 days, adult chickens. 6--8 only. This will not only make full use of the housing space, but will not cause diseases due to air pollution and excessive humidity. 4. Do a good job of immunization. Marek's vaccine inoculated at 1- to 3-day-old; Newcastle disease II-family seedlings sprayed at 7- to 12-day-old days; 35 days old; and once again; 2-to-5-week-old vaccine for infectious bursal disease and Infectious bronchitis vaccination; 2-month-old chickens were bred with the Newcastle disease I strain vaccine. (b) Feeding and management of large chickens Chickens are chickens 60 days of age or older. The management of the chickens in this stage is the key to determining the pros and cons of egg production. 1. Chicken limits nutrients. Mainly limit the nutritional level of chickens in the diet, appropriate to reduce food intake, protein and energy concentrations, so as not to affect the amount of egg production in chicken fat, the general rural areas mainly in rice, corn as the main feed. 2. Seek for food. In rural areas, large chickens can be kept in the wild, allowing them to freely feed on green grass and insects. Through grazing, both chickens can be controlled to be over-fat and egg-laying chickens can produce environmentally-friendly, non-polluting and nutritious eggs. Can reduce feeding costs. 3. Supply gravel. For cage raising or house feeding, flats or sand pools are set in the sports grounds, and any chicken is allowed to feed gravel or sand bath freely, which is not only beneficial to enhance the digestive function of chickens, but also reduces the invasion of parasites. 4. Diet formulation. During the egg production period, the preparation of the Minjiang green shell layer was 61% corn, 5% wheat bran, 18% soybean cake, 4% fishmeal, 7.8% stone powder, 1.8% bone meal, 0.4% salt, and 2% premix. The above recipes are for reference only. The chicken farmer should adjust the diet formula based on different resource conditions in different regions. 5. Reasonable lighting. The length and intensity of the illumination time can directly affect the maturation and production performance of the Minjiang green shell layer. Medium chickens generally shine. 10--12 hours is appropriate, and laying time for laying hens is usually 10-17 hours, which should not be too long or too short. 6. Prevent diseases. Inside and outside the house should be kept clean and hygienic, summer and autumn to ventilation, summer cooling; spring ventilation and ventilation. To remove excrement and food residue leftovers in time. And often cleaning and disinfecting food waste and drinking fountains. It is also necessary to observe whether the spirit, appetite, etc. of the flock and the color and traits of the feces are abnormal. Timely treatment of diseased chickens to prevent the spread of disease in the flock, usually in the drinking water to add antibiotics, allicin and other drugs to prevent disease, but mainly to do a good job of immunity and cleanliness.
