The goats are 'free' but require expensive fencing and supervision. Otherwise they'll just wander off and eat the tastier food crops or household plants. Goat meat and milk processing is not as automated as it is for cattle, chicken, pigs. Free-range goats with a GPS-based pain collar could be a solution.
