Main reason of low laying rate by indigenous hens is due to their desire to brood the eggs and the prolong rearing period.
A hen normally takes about 21 days of brooding and 75 days of rearing.
Hence, by reducing their desire for brooding, indigenous hens can produce an average of 200 eggs per year.
Reasons for hens’ desire to brood are hormonal changes, availability of light & heat and chest exposures with their eggs.
To cut down the brooding desire, the hen has to be taken out from the nest and place under a basket or cage at cool and well-light location, providing enough food and water. By doing this, the hens will lay eggs again after 14 days.
If chickens are raised naturally, chicks rearing period will be prolong and production tends to decrease.
By rearing young chicks separately, hens can lay more eggs from 3-4 times to 5-6 times a year.
In addition, chicks can also be prevented from predators such as dogs, crows and eagles.
