A hen may lay one egg per day for at least 30 days or may skip some days. However, this number varies from hen to hen and from season to season.
Note that local chicken lay more eggs in the wet season than in the dry season. This is because of the availability of juicy greens, insects, worms etc.
Eggs should be kept well in cool dry places because higher temperatures, like those in dry seasons, affect the development of the chick inside the eggs.
In addition, the egg may lose a lot of moisture. Note that an egg that has lost 12% of its original weight after 18 days will not hatch. If it does, the chick will be small and may not survive.
When eggs stay for more than seven days in a nest, they tend to lose their hatchability. An egg loses about 4% hatchability every day it is stored beyond seven days.
This is why you need to be keen to identify the eggs laid earlier by the chicken and either eat or sell them. This means that if a hen has laid 30 eggs, you may give it between 10-15 eggs laid during the last days.
