Never heard of such a thing till now? Me either.
Yip....these goats actually faint when startled and look like they have rigor- mortise when they fallm over. After a few seconds....they get up all dazed lookin. THe farmers used to use them to protect their sheep. They would put these goats in with the sheep and when the bad wolf came around, the goats would faint and get eaten and the sheep would get away. A bad deal for the goats, but a good deal for the sheep.
