I'd also like a goat in milk. If we ever get a farm, hubby wants a cow, perhaps two (for rotation) to keep us in milk. For our current little slice of God's creation, we can really only have a goat, preferably a miniature or dwarf one.
However, this year, we are considering pigs. My garden has diminished in quality over the years despite crop rotation and compost/manure additions. My father used to let his garden rest every 7 years. I am considering this year to be a year of rest for the garden. In its place, we're thinking of some spring pigs to till it up and fertilize it. The pigs will then be butchered in Autumn and distributed to my family.
