Egg Laying

Another hormone released by your hens is responsible for laying eggs. Through the amount of light your hens are exposed to this hormone control the egg production.

The hormones which control the egg production, dwindle laying eggs of your hens when the days shorten. They can stop laying eggs for a certain period of time.

Generally this happen when most of your hens molt their old feathers until new feathers grow in. They will start laying eggs again regularly after growing their feathers.

During this period the energy of your hens is devoted to grow new feathers and they can’t use the energy for producing and laying eggs. They will continue laying eggs again after growing new feathers.

Other Factors

Hormonal signals are not always the reason of stopping laying eggs or molting. Sometimes other factors also influence the egg production or molting.

For example, your hens may lay less eggs, stop laying or molt if they don’t get sufficient amount of nutritious food or clean water. Egg production from your hens can also be interrupted if their regular diet become too low in calcium or protein.

So, it will be better if you can prepare a special feed mixture for your laying hens that will contain all types of necessary nutrient elements and vitamins. Thus you can get fresh eggs throughout the year.
