1. When observing the flock every morning and evening, pay attention to the chickens that are off the shelves late in the morning and early in the evening.
2. Chickens suffering from yolk peritonitis, because the yolk solidifies in the abdominal cavity, the entire abdomen becomes hard and loses its elasticity. The gait is a little unstable, and it looks like a duck staggering when walking, often lying on the ground. It should be eliminated.
3. Due to ovarian degeneration, dysfunction, sexual variation and masculinization, sometimes "hen crowing" appears, which should be eliminated in time.
4. Eliminate the sick chickens in time.
5. If you are not able to grasp the above inspection methods on time, you can separate and raise them separately. In the early morning, check the cloaca birth canal one by one for eggs to be laid. After 3 consecutive days, there is no egg for 1 day. , Can be considered eliminated.
6. The knocked-out chickens have a feeling of abdominal pressure, often enter the egg box and hug, but do not see the eggs. Hold the cloaca birth canal with your fingers, and feel eggs, especially after 4 pm, they often fall in the egg box and do not want to pick them. The food is not a brood chicken, and this kind of chicken should be eliminated.
7. When exploring the abdominal cavity, most chickens have irregular foreign bodies.
8. In the mating season, when the ground is not dry, observe whether there are mud traces left by the trampling on the back of the rooster during mating. For those hens with no mud marks, bright feathers, and plump appearance, most of them are culled chickens suffering from certain chronic diseases.
9. During the egg-laying season, check the feces in the chicken house every morning. The feces of normal laying hens are plentiful, soft and moist. Eliminated chickens that do not lay eggs, because they eat less food and are slow to digest, their feces are mostly dry and thin.
