Why do ducks lay soft-shell eggs

The reasons why ducks produce soft-shell eggs:

1. Lack of calcium in diet, or imbalance of calcium and phosphorus, or lack of vitamin D3.

2. With the continuous high yield for a long time, it is difficult to supplement the calcium from the feed.

3. The ambient temperature is too high, the ducks lose their appetite, eat less feed, and calcium is in short supply.

4. The duck is frightened, which disturbs the nervous function and endocrine gland function, which hinders the formation of calcium in eggs, or eggs are excreted too quickly to produce soft-shell or thin-shell eggs.

5. The stress factors caused by the crowding in the duck house are heavy ammonia, poor ventilation and uncomfortable laying of soft-shell eggs in the duck house.

6. When suffering from infectious bronchitis or duck plague, the function of absorbing calcium is reduced, and at the beginning of the disease, the eggshell becomes thinner or the egg shape is abnormal.

7. improper use of drugs, the general dose of drugs should be determined according to the weight of ducks, when the drug is too large, it is also easy to produce thin-shell eggs or soft-shell eggs.

8. Stress such as sudden changes in weather and duck vaccination can also produce thin-shell or soft-shell eggs.
