There can be a variety of reasons why hens don't lay eggs, here are some of the possible reasons:
1.Physiological factors: After the laying period of hens, the ovaries will gradually shrink, resulting in a decrease in estrogen secretion, which affects the development of follicles and the formation of eggs. In addition, when the hen enters the moulting period, it will also stop laying eggs due to changes in hormone secretion.
2.Nutritional deficiencies: If the hen lacks adequate nutrients, such as proteins, vitamins and minerals, it will affect the normal function of the ovaries, resulting in a decrease in egg production or a cessation of egg production.
3.Diseases: Some diseases, such as avian influenza and Newcastle disease, can affect the reproductive system of hens, resulting in reduced egg production or cessation of egg production. In addition, some parasitic diseases can also affect the reproductive system of hens, causing a decrease in egg production or a cessation of egg production.
4.Environmental factors: If the hen is in an uncomfortable environment, such as too high or too low temperature, too high or too little humidity, etc., it will affect the normal function of the ovaries, resulting in a decrease in egg production or a cessation of egg production.
For these reasons, the following measures can be taken to help hens resume egg production:
1.Adjust the feed formulation: provide the hens with adequate nutrients, such as protein, vitamins and minerals.
2.Strengthen feeding management: maintain a suitable environmental temperature and humidity, and regularly clean the chicken coop and drinking utensils.
3.Diseases: Timely detection and disease of hens, such as avian influenza, Newcastle disease, etc.
In conclusion, there can be a variety of reasons why a hen does not lay eggs, and measures need to be taken to help the hen resume laying eggs for specific reasons.
