I raise and show angora goats and they are very hardy. With no hay and little grazing, a mature female gets 3lbs of Nauman (angora goat feed) a day. I trim hooves once about every 1-2 months depending on the state of them. Because i'm in Texas, they do have fans on them in the summer, but other than that they are fine. Adults are not jumpers, and don't really even test fences. They get sheared twice a year, and you can sell their hair, called mohair, to any buyers, or you can use it for yourself. Unregistered goats are a little hard to come by, but will run $50-$150, registered kids are about $300 and up... Provide a goat mineral block, fresh water and feed, and you'll be good to go. This breed is pretty laid back, but are a bit skittish if you don't handle them on a regular basis. They will need a seperate pen and shelter from the chickens, as chicken feed can kill any goat.
