Boil the eggs in boiling water for about 9 minutes until they are hard, then rinse with cold water. Peel the eggs, cut off the upper third on the pointed side. Remove the egg yolks. Cut the egg whites at the cut edges in a jagged fashion. Pass egg yolks through a sieve, mix with mayonnaise and milk.
Pour the egg yolk mixture into a piping bag with a central perforated spout, squirt the mixture into the eggs and put the pieces together. Wash and clean the carrot and cut small pieces for the "beaks". Cut the olive into small pieces.
Garnish olive pieces as "eyes" and carrot pieces as "beak".
