Angora goats are an easy-keeping breed that produce copious fiber (enough for two annual shearings) and have only basic shelter requirements.
These breeds make great livestock guardian dogs, though you need to follow a few important rules to make full use of these working dogs.
Though "natural" is always a good goal, expect to help honeybees through the winter with supplemental feedings to sustain conditions not found in nature.
When choosing what sheep to raise, consider a heritage breed. You can meet your own livestock needs while also ensuring breed diversity.
