I see the goats being sold on the websites of the specific ranch going for around $600. I see the ones being sold as food for as low as $50. I'm guessing the food goats and the $600 goats are some how different? What determines weather the goat is food quality or $600 quality? And what what is the use of these $600 goats? I'm guessing people are taking them to goat show rings, much like how people do with dogs?
