I have a 50 acre farm that is not being used at the moment. In the next year, I would like to get a few milk goats, a few sheep, some chickens, ducks, and a potbelly pig (we already have the pig). Obviously these animals have different nutritional requirements from a feed perspective, but I'm wondering if there is any problem with them using the same grazing/living areas? We don't intend to sell the milk or milk products. My main concern is keeping them as warm as possible in the winter.
