Hi, We have the equivalent of a 1/2 acre block, however it has 2 houses and 2 large sheds on it, plus a large portion fenced off for vegetable growing, and a large unfenced section with young fruit trees. We have an old horse stable that functions as a chook pen (12 chooks inc. a rooster). We would love to explore some ideas for an animal that would reduce the amount of mowing. I am considering a pair of lambs that could be raised for sale when they became too big for the area. I am also wondering about the viability of guine-pig proofing our vegetable garden (it is already fenced, but would need better fencing at a lower height, and all gardens are raised) and letting a couple of guinea pigs use it as a run. I have never been a fan of Guinea pigs as a pet, however I can see there use in keeping grass down.
