Chickens lay soft-preserved eggs (also known as eggshells with crunchy eggs) usually caused by the following reasons:
1. Insufficient nutrition of chickens: During the egg laying process, chickens need sufficient calcium and vitamin D to form hard egg shells. A lack of these key nutrients in a chicken's diet can result in thin or weak eggshells.
2. Eggshell synthesis problems in chickens: Some chickens may have eggshell synthesis problems when laying eggs, causing the eggshells to fail to form a hard structure normally.
Here are some ways to solve the soft-preserved egg problem:
1. Provide a balanced diet: Ensure that chickens receive adequate calcium and vitamin D. This can be achieved by providing the chickens with high-quality feed or adding feed supplements containing calcium and vitamin D. Chickens can also be given bone meal, shell meal, cracked eggshells, or other calcium-rich foods.
2. Control the chicken's diet: Avoid giving chickens too much high-protein food, because too much protein will affect the absorption and utilization of calcium in the chicken's body.
3. Drinking water management: Ensure that the chickens have a clean, fresh drinking water supply. Electrolytes and minerals in the drinking water can be added to help the chickens maintain acid-base balance.
4. Disease management: Some chicken diseases, such as chicken infectious anemia, may also lead to the production of soft-preserved eggs. Sick chickens need timely medical treatment to treat related diseases.
If your chickens are chronically producing soft-shell eggs, it is recommended to consult a veterinarian or agricultural expert for professional advice and guidance on your specific situation.
