Chickens will lay eggs only when the light available is increasing or at 
best steady.  In the wild this generally limits production.  If the chicken
goes "broody" and starts to sit on the eggs to hatch them, she'll stop 
laying.  Removing the eggs does help to prevent her from going broody.

However, in commercial production where the light regime is controlled and 
the eggs are removed, a chicken can lay over 250 eggs a year regularly and 
over 300 under top-notch performance conditions.
