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.
Between 150 and 200 milligrams is considered safe in most studies, but many doctors recommend pregnant women avoid caffeine altogether. Thatâs because no matter how long caffeine stays in the body of the mother, it might stay even longer in the baby. The American Journal of Obstetrics and Gynecology found that when women drink 200 milligrams or more of caffeine, they double their risk of miscarriage. However, other studies dispute that.
