Serena Williams. It's another milestone week for the WTA with Serena Williams hitting 157 consecutive weeks at No.1, passing Martina Navratilova for the second-longest streak at No.1 in WTA history.
Most hens will start laying between 5-7 months of age. They will lay best at 1 to 2 years of age. All pullets (female chicken under 1 year of age) lay small eggs at first and after a while will lay larger eggs. Younger hens will lay 1 egg every 3-4 days. A hen 30 weeks old can lay 2 eggs every 3 days. Some have been known to lay an egg a day.
Tipically, a well fed chicken, with proper living conditions and from a good breed (such as Isa Brown) should start laying eggs at week 19 or 20. It will reach its peak of production between week 25 and 30, then it will decline but the bird will keep laying eggs until a very old age.
