Goats are usually purchased from goat farms where breeders raise and sell them. Some 4H or other farming groups have goat sales that may have a wider variety of breeds available.
Many goat farms specialize in just one or two types of goats, so buyers should research breeds ahead of time. Livestock auctions also have a variety of different goats for sale, but it is a difficult environment to purchase from because of the limited time and information available. People who want a goat as a pet or long-term producer should avoid such auctions. The safest place to buy a good goat from is a reputable breeder or farm with a good reputation.
