I've got an acre. About half of it is a grassy area with half a dozen fruiting trees, catalpa trees, willows, walnuts, roses, maples, and a few others. The grass is modestly mixed with plantain and clover. I'd really like to plop a few grazers out there to enjoy the space, and I can enjoy their company. I'm not really looking to make money or substantial use off the animals, I'd like them to graze as much as possible year round, leave the trees alone (some fruit trees are dwarf and semi-dwarf and low to the ground), and generally be pleasant to keep. I have rabbits and chickens already roaming this area. I originally wanted goats, but have since learned about their tree-destroying abilities. And I'm not prepared to fence off 10+ trees. I started to think about sheep, but I know nothing about them. Are they sociable? Do they enjoy a human's company? My neighbor suggested alpacas, but I've read that they're more like cats and aren't overly fond of humans. As I am keeping the animals mostly for pleasure and companionship, I'd like some kind of personal interaction with the critter. Goodness knows I already don't get that with my hens and rabbits! Any thoughts on an animal that might fit my wants here? And on a side note, I was curious about how large of a pasture area might sustain 2 or 3 small-medium goats, without being trodden to mud (if possible!). I have one 500sq ft. (50x100) area I could use or a 320sq ft. (40x80) area I could use to pen them in. Thanks for any input!
