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.
Female chickens (hens) generally start laying eggs at around 20-24 weeks of age. Some breeds take longer. They don't need a rooster to lay eggs and if you are lucky they will â¦ lay an egg per day. Again this depends on the breed, with some chickens laying an egg every few days.hus: 3 chickens will lay 1 egg in 1/2 of a day. Then it follows that 3 chickens will lay 2 eggs in 1 day. Now, if we allow those 3 chickens three times as long (3 days), they will produce 6 eggs. 3 chickens will lay 6 eggs in 3 days.
