Chickens have a weak digestive system, so it's important to provide easily digestible feed. In the early stages, you can offer half-cooked millet mixed with cooked egg yolk (1 egg yolk per 18 chicks daily). After 10 days of age, gradually introduce 10–20% cornmeal, 8–10% chopped green feed, 1–1.5% bone meal, 1–1.5% fishmeal, and 0.5% water-washed fine sand into their diet. By the time they are 30 days old, you can start feeding them a mix of chopped vegetables and grains like millet, barley, or wheat. It's also recommended to feed them 1–2 times a day with these grains, along with supplements such as bone meal, fishmeal, and shell powder.
During the first two weeks after hatching, add 0.04% furazolidone to the feed daily to prevent diseases like paratyphoid and leukemia. From day 15 onwards, you can switch to adding 0.01% furazolidone or 0.1% sulfamethazine to the feed, then stop for 1–2 days before resuming. At 45 days of age, focus on preventing coccidiosis. Vaccinate against Newcastle disease at 8, 25, and 66 days of age. If any chicken shows signs of illness, isolate it immediately. Also, group chickens based on their growth rate and physical condition to ensure even development.
Maintain proper temperature and humidity depending on the stage of growth. Ensure the living environment is well-ventilated, clean, and dry. Provide clean drinking water and wash feeders and waterers daily. Disinfect them every two weeks using a hot sodium hydroxide solution. Regularly replace the bedding to keep the area hygienic.
In winter, hens need additional lighting to maintain high egg production. Extending daylight to 13–14 hours through artificial lighting, combined with nutritious feed, can increase egg production by up to 22%. From November to January, use 15–60 watt bulbs in the morning (from 5:00 to 6:30 AM), afternoon (from 5:00 to 8:00 PM), and evening (from 11:00 PM to 2:00 AM) to supplement light. Avoid sudden changes in lighting to prevent stress among the flock.
It’s also important to "wake up" Wuji chickens, which tend to stay in nests for long periods. One effective method is to feed them rice kernels in the morning and evening for about 15 days. After that, provide quality feed, and egg production should typically resume within 7–12 days. This helps stimulate their natural laying behavior and improves overall productivity.
Biosafety cabinets (BSCs) are one type of biocontainment equipment used in biological laboratories to provide personnel, environmental, and product protection.
