Animal Figurines

We go to the Messiah every year - my husband attended the Cathedral of St. John the Devine Choir School when he was 8 & 9 and they sang it at Christmas so it's become a tradition for us for 30 years. My 11 year old grandson went with us last year and he said the same thing - why are we all like sheep? I have two of these sheep that I use in my Creche.
