The chocatrice egg was created during the 2008 Easter event by dipping a cockatrice egg in molten chocolate. It could be hatched into a chocatrice during the event. You could not get another egg after you had completed the event. The Easter bunny would say you already have a chocatrice egg you do not need another one.
