Is it a sheep or a goat?!?

After the obligatory watching of the making of a real life princess we headed up to Graves Park for some fresh air. Was lovely to see all the usual animals however this new addition really baffled us.... is it a sheep or a goat? I thought sheep but DH placed his bets on a goat, although I think that was due to its greedy attitude to the food!

Answers on a postcard please!
