The appearance of eggshell eggs in laying hens is a physiological disorder, also known as soft-shell eggs. Normal eggs should have a hard shell to protect the yolk and egg whites inside, but when there is a problem with the egg formation process, it will lead to the production of eggshell eggs.
The main causes of eggshell eggs can be boiled down to the following:
Insufficient calcium load: Chickens need enough calcium to form a hard eggshell. If the amount of calcium in the feed is insufficient, or if the chicken is not able to absorb enough calcium, it can lead to incomplete eggshell formation.
Vitamin D deficiency: Vitamin D is an important nutrient that helps chickens absorb and utilize calcium. If the amount of vitamin D in the feed is insufficient, or if the chicken body does not make full use of vitamin D, it can also affect the formation of egg shells.
Illness or stress: Certain diseases, infections or stress situations can affect calcium metabolism and eggshell formation processes in the chicken, resulting in weak or incomplete eggshells.
*The method of eggshell eggs mainly includes the following aspects:
Dietary modification: Make sure the feed contains sufficient calcium and vitamin D. Some supplements rich in calcium and vitamin D, such as stone meal, shell meal, fish bone meal, etc., can be added to the feed. At the same time, the feeding environment should be kept dry and clean to ensure the freshness and hygiene of the feed.
Vitamin and mineral supplements: Some vitamin and mineral supplements, such as vitamin D, calcium, phosphorus, etc., can be added to the drinking water to help the chicken absorb and utilize calcium.
Prevention and disease: timely vaccination and prevention of common diseases to maintain the health of chickens. If other abnormalities are found in the chicken, such as loss of appetite, irregular feathers, etc., you should consult a veterinarian for diagnosis and ** in time.
It should be noted that ** eggshell eggs need to consider multiple factors such as feed, nutrition, environment and health. Therefore, if you encounter the problem of egg shells, it is recommended to consult a veterinarian or professional in time to formulate a corresponding ** plan according to the specific situation.
