Other Animals on the Farm
In addition to the cows, Mama Anna had goats, sheep (I'd post a picture, but I think you've seen them before), chickens, beehives and bunnies like this one. These animals served as sources of meat, milk, cheese, honey and, via a complex system of drying and preparing dung, fuel for cooking and heating.
We also saw a dog house. When we asked about the dogs, we were told that they are guard dogs, not pets. They are released at night to protect the animals from predators of the four-legged (and two-legged) persuasions.
The animals were strictly for the village. They were not for trade. For trade, Mama Anna capitalizes on America's favorite addiction.
