It is hard to make money on either on your scale. The better money would be goat milk if you get a customer (and can
sell raw milk, check your
local laws!) Goatmilk goes for $10/gallon here. If you are willing to milk daily. Just the savings from not buying milk for your family is probably worth more than you would get for 2-3 lambs a year.
Sheep are especially susceptible to predators, and once they find out how easy and tasty lamb is they just keep coming back until the herd is gone. You need serious protection for sheep--either locked in a barn at night or guard dogs. Goats are a lot tougher. You will still have issues, but adult goats can defend themselves and their kids.
Goats are impossible to keep in fences, you have to make them want to stay (well fed and not bored). ALWAYS have at least 2 goats (one goat will always get bored).
Some goat milk tastes horrible, some tastes wonderful (better than commercial cow's milk). Always taste the milk before you buy the goat (or cow) if it is fresh. If it tastes bad, sell her and try again, or keep her as the nurse nanny for all the babies and keep the milk from the other(s).
