To conserve heat, on a cold day, the goats have learned to stand very tightly close to each other in a circle. They behave exactly as the emperor penguins seen in the movie March of the Penguins. They are a really close herd and have a strong social bond. They nurture each other and feel loved by us as we care for them. They also feel at home in their environment, close to us and to the house. That is why they are so happy and at peace. We see this connection as precious and it reminds us of our co-existence on this awesome planet.
