I have a nice fenced in area just adjacent to my back yard that is growing grass faster and thicker than I can possibly keep up with, with my push mower. The fence is about chest high, incloses an area about 1/4 the size of a football field, is new and very stable. I was seriously thinking about putting a couple of nanny goats in this area to help with the mowing chore? I'm not interested in raising any additional goats so I thought a couple of females would suffice...Ok, my question is this: since I've never had goats before and know absolutely nothing about them, are they hardy animals, what about vaccinations and how often, what kind of feed/hay and shelter will they need? The area to the South of my fence is about 200 yards to a creek and wooded area, do I need to be worry about preditors killing them or are they self sufficient if full grown? Thanks in advance for any and all suggestions or comments.
