This is the wire I used. You need real good wire to keep your animals IN and other animals OUT. Bear in mind the number one predator of sheep is dogs. In a suburban area, there will be lots of dogs. Hopefully people keep them on their own property, but some people are not very thoughtful of others. We have Great Pyrenees livestock guard dogs because of coyotes. On a small acreage like yours, you can probably put your sheep up securely at night and be ok. But you need a GOOD fence. Put up a good solid parameter fence, then cross fence into what pastures you want. You won't put it all up at one time, so buy a roll or two, with T-posts and put it up. Then do the next stretch.
