First, the environment causes (a) changes in lighting procedures or light intensity. If you just change the color, suddenly stop the light, the light time is shortened, the light intensity is weakened, the light time is irregular and so on. (b) Serious shortage of ventilation. For example, mechanically ventilated chicken houses have a long-term power outage in hot climates, and they do not ventilate for a long period of time in order to keep warm in winter. (c) The weather is hot. The weather was hot for several consecutive days, resulting in a sustained high temperature and high humidity environment. (d) Severe weather attack. Failed to prepare or prevent it in advance, suddenly encountered heat waves or cold currents. (e) Long-term water cut off.

Third, the chicken disease, a variety of acute infectious diseases will cause a sudden drop in egg production. For example, if a chicken is attacked by a highly toxic Newcastle disease, the egg production is often reduced by more than 50%. Infected egg production decline syndrome can also reduce egg production by more than 50%. In addition, chicken infection laryngotracheitis, cholera, etc., will make the egg production rate dropped significantly.
Fourth, poor management of chicken suddenly surprised, such as abnormal sound, suddenly start the fan, sudden shaking of light and shadow, change of keeping staff, vaccination and feeding deworming drugs, will cause decreased egg production.
Only by pinpointing the reasons for the sudden drop in egg production can corresponding measures be taken. However, it should be pointed out that in large-scale chicken production, because the number of days of continuous egg production is not the same, regardless of the number of consecutive egg production days, there will be a day of production after the end of the production of eggs, such as production of chicken in a certain The accidental increase in the number of eggs produced a sudden drop in egg production. In this case, if there is no abnormal phenomenon in the flock, the egg production will return to normal soon and do not panic.
