White goats on a November morning

Early morning, at the main door of Villa of Castello/La Petraia  Are you wondering what are two goats doing in front of the main entry of the famous Accademia della Crusca (the Accademia is the most important center of scientific research dedicated to the study and promotion of Italian language and it is located in Florence, at the Medicean Villa of Castello/La Petraia)?

I don't know, but they were so nice ... and polite (more than ....!....)
