LoneCowboy, there are some concerns about liability, because the goats are usually working near roads in a rather densely populated urban area. The current owner told me a story that made my hair stand on end..not long ago a deer apparently crashed through one of her temporary fences, and the goats ended up following right out onto a busy boulevard. They ended up on the side of the road, around a blind-curve. Thank heavens nobody struck them with their car or got into an accident, but I can just see the lawsuits if something like that were to happen!
Also, her customers often have children who want to go "see the goats" and have even opened the fence to get in there and pet them. As far as I know, she doesn't make customers sign a waiver freeing her from liability if a child were accidentally injured. That also makes me nervous! The goats are sweet and gentle, but when startled or held, can tend to kick (They are mostly Boer, and fairly strong!).
