Precautions:
1.
Large-scale chicken farmers can choose to check chicken manure at a fixed time every day. If the chicken manure is dry and hard, it can be eliminated, because the chicken manure at the peak of egg laying is generally soft and wet.
2. Look at your stomach and wash your chicken
Sometimes chicken farmers will find that a group of pregnant chickens often appear in the chicken farm. At this time, farmers' friends should touch the chicken's abdomen with their hands. If the abdomen of chickens is as soft as jelly or the abdomen is big and hard, these chickens usually have yolk peritonitis or tubal cyst. These chickens have basically stopped production and can be eliminated in time once they are found.

The molting of chickens is actually a normal physiological phenomenon. Basically, every time a chicken completes an egg laying cycle, it will start molting around 10. However, some laying hens with low egg production may start in August, with a long molting cycle, and such chickens can also be eliminated in time.
4. Eliminate chickens with ovarian inflammation.
Chickens with ovarian inflammation can hardly see the appearance symptoms in the first few months. After the peak, observe the laying situation of chickens every day. Mark the cage where 4 chickens lay 3 eggs or 3 chickens lay 2 eggs for 3-4 days. This situation persists. Every morning before laying eggs, touch the chickens in these cages to see if there are any eggs, and the chickens without eggs will be eliminated directly. Repeat this operation once a year in January and February.
