Some chickens lay an egg almost every day, others every 1.5 to 2 days. Younger hens (called pullets if less than one year old) will lay smaller eggs at larger intervals until they reach maturity.
The caffeine effect. There are several reasons why women should limit their caffeine intake to less than 200 mg per day during pregnancy. Caffeine is a stimulant that influences the sympathetic nervous system to give you a buzz, sending messages to and from your brain more rapidly.
Pregnant women should have no more than 200mg of caffeine a day. One mug of instant coffee contains around 100mg of caffeine. High levels of caffeine can result in babies having a low birth weight, which can increase the risk of health problems in later life.
