After frequenting this very interesting website for a couple of years I finally joined up a few months ago.
My wife and I live with our young family on a 2.5 acre farmlet in South Otago. The property is a bit run down but if it wasn't we wouldn't have been able to afford to buy it.
We run a few each of goats, sheep, pigs, and cattle along with a varied assortment of hens and ducks. My wife is a keen gardener. We are attempting, with some success, to be self sufficient in meat, milk, eggs, and vegetables. The place is just big enough to wish that it was a bit bigger but with my fulltime job I don't have time do to all the farm jobs that need to be done so development works are progressing very slowly.
You sound like us, only we started on this run-down block later in life. Only regret is that we didn't start sooner! We've been self-sufficient-ish for about 15 years now, each time moving up (twice so far) to a larger block. 4 ha now, and wishing we had more space, simply for growing more of our own livestock fodder. Wouldn't want to expand numbers at all.
DH with full time work away from the farm and me with a bad back mean things take a reeeeeeeeally long time, which can be frustrating at times.
