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.
In high doses, caffeine can affect fetal breathing and heart rate. If you are pregnant, or planning to become pregnant, consider your options (e.g. eliminating caffeine or limiting intake to 200-300 mg per day). Discuss these options with your clinician.
