1. Increase feed nutrition. After a long period of egg production and hot summers, the chickens are very tired. After the autumn, they should feed more animal protein feeds, supplement chickens that have not yet been moulted, continue to lay eggs, and promote the feathered chickens to grow into feathers quickly. Recover production as soon as possible. Since the chicken's nerves are very sensitive at this time, slower spreading must be added to the more nutritious feed so that the chicken's nerves are not stimulated and the moult ceases production. 2. Update in time. General laying hens only use 1 to 2 years, and they should only feed for 3 years. First, the old and the weak hens were bred and raised separately. They were raised before the moulting. The rations were supplied according to the hen feeding period and the light was increased to 14 to 16 hours. The hens were eliminated and their moult was delayed. When eggs drop below 60%, they can be sold. 3. Promote synchronous moulting. Reduce the light from the original 14 to 16 hours to 8 hours or less (or change to dim light), stop feeding compound feed for 10 days, and then feed the roughage such as chaff flour and straw powder, normally supply drinking water, and add in the diet 1% to 1.5% calcium sulphate (gypsum) instead of mineral feed, 5-8 days will have a large number of layer moults have to moult, 10 days later to feed grain, sorghum and other pellet feed, each chicken fed a day 50 ~ 100g of green vegetables or squash, 3 weeks later gradually return to compound feed and light, generally after 4 weeks the new feather can be long and gradually begin to lay eggs. 4. Do a good job of preventing pests. The climatic conditions in autumn are suitable for the activity and reproduction of pathogenic bacteria. Chickens are prone to infectious diseases. In this case, a vaccination should be carried out and the parasites (especially roundworms and aphids) should be driven off. For each kg of chicken body weight, 0.4-0.5 g tetradiimidazole is mixed in the feed to feed chickens; or each chicken is fed 15 g pumpkin seeds and 15 g fried white. 5. Prevent colds and chickenpox. After the fall, the weather turns cold, especially if the temperature changes in the morning and evening. Chickens are prone to catch cold. The prevention of chicken disease is first of all to prevent colds. Chickens that have colds will reduce their resistance, and it is easy to develop other infectious diseases. Therefore, it is not advisable for chickens to be put on the playground. Most of the fowl pox occurs in the late autumn when it is opened, and it is mostly infected with young chickens of the current year. To avoid this disease, prevention should be done well. The emphasis is on mosquito prevention and moisture prevention. China Agricultural Network Editor
