We will be getting some icelandic sheep sometime between now and spring, I will be working for them. My questions are basic. First since the lines we are getting are 'milky' and produce good milk, is it like milking a goat? My thought is that they will be more wiggly. Second is about fencing. We have 4 strand hotwire all around the feild that is about 4' tall, the bottom 2 strands are lower. Will this work to keep sheep in?
