A hen can only lay one single egg every day and at the most seven eggs per week; however, most chickens lay fewer eggs. In general, majority of the standard breeds of chickens lay between 180 and 320 eggs a year for their first year of laying eggs.

The female chicken usually lays one egg after every 25 hours, which is equivalent to a maximum of seven eggs a week. The rate at which the eggs are laid is however dependent on the time of the year, the breed of the hen, the diet of the hen as well as its age.
A chicken lays one egg in a day, and can do so for a whole year.
