With the expansion of farming scale, there are more and more chicken houses, and for these intensive farming, once the disease occurs, the loss is incalculable. Therefore, it is necessary to discover early, prevent disease, strengthen physique and promote high yield.

In daily management, we need to pay attention to these signals as early as possible:
The Ratio of Egg Laying to Afternoon Laying in Chicken Groups
Normal chickens lay eggs every morning, accounting for more than 80% of the total number of eggs laid throughout the day. The earlier they lay eggs in the morning, the more healthy they are.
If it is found that the time of laying eggs in the morning is delayed, the total egg production remains unchanged. This is due to stress stimulation, endocrine dysfunction, or liver and kidney dysfunction, resulting in reproductive system dysfunction, follicular lag, or slow egg white secretion.
At this time, stress should be identified and eliminated, endocrine system and liver and kidney function should be regulated, so as to restore normal level and physiological function, so as to ensure stable and high yield.
Changes in Eggshell Quality
In the production of laying hens, the change of eggshell color directly reflects the physiological state of fallopian tube system. Once the color of eggshell turns white, sand-covered eggs or black spots are found, this is a symptom of the continuing development of the disease, which is the forward development of the delayed laying of eggs.
Most of them fail to attract attention because of the earlier delay in laying eggs. Stress factors have not been eliminated or continue to strongly stimulate the body, viruses or bacteria into the blood, resulting in increased tubal inflammation and even tubal bleeding (due to higher body temperature in chickens, oxidative blackening after tubal bleeding, tubal folds affect the timely precipitation of black spots). In the eggshell, therefore, often lead to aggravation of inflammation before appearing on the surface of the eggshell, secretion disorders caused.

Common eggshell signals are: white eggshell, Yinyang eggs (blocked pigmentation), sand skin, thin shell (inhomogeneous carbonate deposition or blocked secretion).
Changes in the Number of Laying Hens
We tend to pay attention to the reduction of egg weight (each egg weight becomes smaller), and ignore that some chickens "only eat and do not work", which is more serious, because every chicken consumption every day, need more than ten chickens to produce profits to offset, your profits are so lost.
Therefore, we should pay attention to the production data every day, according to the total egg weight and average egg weight, grasp the production status of chickens, analyze the number of stopped or low-yielding chickens when necessary, and take necessary treatment measures.
Changes in feed intake
In the actual production process, as long as our eyes see that our chickens eat less, our chickens'feed intake has also decreased by about 10%, which is too late.
Therefore, we need to know the daily feed of our chickens, accurate to 10 kilograms as a unit, that is, the error of up to 10 kilograms of feed, so we can easily find changes in the feed intake of chickens, only in this way can we find problems early and solve them in time!

Changes of Population Weight of Chicken
In the current laying hen farming, most of them can weigh the chicken population by random sampling during the brooding period. But after entering laying eggs, there are few people who can weigh and control the weight of chickens, especially the individual breeders, which are easy to ignore after laying eggs.
In fact, the change of laying hen's weight is very important after parturition. We must weigh the laying hen once a week and compare it with the feeding standard manual to see if it meets the standard. If you lose weight, you either have inadequate food intake or feed supply, or you have intestinal diseases that lead to inadequate digestion and absorption, which will directly lead to a decline in production performance, or even no peak egg production.
Listen to the sound of chickens
Every night before going to bed, you must go to the chicken house to listen to the movement of the chickens. Whether there is no stop turning and difficult to be quiet, whether there is abnormal respiratory tract and show rale or dry cough.
Look at the excrement
The observation of feces should be based on color and shape.
More color changes, such as red, should pay attention to the single or mixed infection of coccidia and necrotizing enteritis; yellow butter-like feces should pay attention to influenza and other pathological changes; white egg white (feel smooth) should pay attention to dysentery, bursitis; and white lime (feel rough) must be ventilated or renal branch; green should also be dried separately. Green and sparse green, dry green is generally seen in flora disorders, sparse green is seen in viral infections; and in recent years, more and more black feces, mostly caused by mycotoxins, mixed with a variety of bacteria or a combination of enterotoxic feces.
However, for the shape of excrement, the normal shape of excrement is that when it falls from the cage, the excrement will be patted like cow dung with a layer of white uric acid on it; if it falls into thin strips and dries, it will be caused by slow peristalsis caused by intestinal bleeding or excessive absorption of water in the intestinal tract due to excessive retention time of excrement in the intestine. Dilute dung: As long as the dung falls down and falls loose, it will not form into thin dung and water-like dung, which is caused by intestinal dysfunction and edema, resulting in the intestinal tract unable to absorb water.
