A certain breed of cow has its first calf on its second birthday and another on every birthday thereafter. All calves are female. Stella's cousin Jeroen (Ye-roon') is the proud owner of such a cow; her name is Agatha. Agatha was born on New Year's Day 2005. If Jeroen kept Agatha and all of her calves and their calves (and so on) that were born before the Summer Olympic games in August 2012, how big would his herd have been??
