We are raising pigs, you saw the pics from jmac, beef cattle, goats, chickens, ducks, rabbits and just purchased sheep. Our son is a member of 4-H and that is the reason for the sheep. He will show a few next summer and sell them in the 4-H marketplace at our county fair. They fetch a good price and the money will go toward animal feed, hay and doctor's visits, as you need a vetrinarian to check the animals out and issue a clean bill of health to bring them to the fair. Any sheep leftover will go into the freezer. Also, I am planning on learning to spin the wool into yarn. Another skill learned is always a good thing.
As for goats, they are easy keepers and you can make soap with their milk, as well as, drink it.
