What bja105 said.
I've kept a small flock of sheep for nearly 20 years now. Biggest I ever got was 6 ewes and a ram, average was 4 and right now I'm down to 2.
Have I made any money at it? Nope, but that's not the point for me. I've got 4 acres total, a bit over 3 fenced and I have to buy hay, so I'm never going to make money. I figure if I break even and put a lamb in my freezer for free or nearly so, I've done good.
I started out with Shetlands that I bought from friends who's health no longer allowed them to deal with animals. Kept Shetlands for a lot of years and got a lot of lambs out of them. Most years I was able to sell raw fleeces for enough to cover the cost of shearing.
The ladies that sheared for me were cutting back and while they were still willing to do my small flock, I could see the handwriting on the wall, so three years ago I started shifting over to Katahdins, which are a hair sheep. They're also considered a "primitive" sheep and require very little in the way of veterinary care and are easy birthers and good mothers. I used to think the Shetlands were tame, but these Katahdins are darn near as tame as dogs, even the ram.
The point for me is that I enjoy having them around, it gives me a reason to get out of bed in the morning, the lambs provide quite a lot of entertainment with their antics, they keep the alders from coming back after I cleared them and they're darn tasty!
So, I guess my point is, if you're looking at it as a money-maker, good luck with that. If you just want some lamb for your freezer and enjoy having livestock around, go for it.
And don't believe all the bull-loney about "sheep looking for a way to die". In 20 years, I've lost exactly two adults to unknown causes, and maybe half a dozen lambs.

Edit: I checked my records and it was 20 years ago exactly that I got my first sheep.
