Hi, my family and I were thinking about getting a few goats in our backyard for companionship and milk. We were wondering what breed we should get. We do not want to show our goats, we only live on an acre of land so we want a smaller breed(like Nigerian dwarf or pygmy) and we also live in Minnesota and today's high was -13 degrees not including wind chill and yesterday was -21. I read that both of those breeds come from Africa too. So, what should we do?
