First, look at the chicken dynamics after turning on the lights early. Healthy chickens will show an eagerness to eat when they turn on the lights. For example, after turning on the light, there are a few chickens in thepoultry cage equipmentthat appear to be lazy, do not move, the wings are drooping, and the feathers are unkempt, indicating that the chicken has Disease.

Second, after turning off the lights at night, listen to the chickens. Healthy chickens take a break after turning off the lights, quiet and silent. If you hear coughing and screaming, you may have a contagious disease.

Third, carefully observe the chicken droppings every day. The feces discharged from healthy chickens are strips or lumps with a small amount of white urate (white tips at the end of the feces). The affected chicken will have diarrhea, the mouth feathers will be wet and wet, and the color of the stool will be green, white, or yellow-white-red mixed color and clear stool. At this time, according to the color of chicken feces, the degree of disease and the severity of the disease can be judged.

Fourth, healthy chickens are active and active when feeding, and their appetite is strong. If the chickens are sick, they are dazed, their appetite is reduced, and their food intake is reduced.

Fifth, abnormal egg production is a precursor. Egg laying time, egg production rate and egg breakage rate, as well as changes in eggshell quality were observed and monitored daily. The eggs produced by healthy chickens have good eggshell quality, less sand eggs, less soft eggs, and low egg breaking rate (the egg breaking rate does not exceed 10 thousandths in the case of normal egg production rate throughout the day). On the contrary, if the egg production is reduced under normal conditions, the eggshell quality is not good, and the sand egg skin, broken egg and soft egg increase, indicating that the chicken has begun to develop disease, and should be carefully analyzed to find the cause and take appropriate measures as soon as possible.
