You could make some serious business from this. I know a guy who has a kangaroo farm, it's not a petting zoo, the Kangaroos can go wild around the premises, and they are very friendly and like people. His is kind of a petting zoo except they are not enclosed. You could do this and give discounts to people who pay in Bitcoin
I'm pretty sure a lot of people would be interested in seeing alpacas.
The alpaca are friendly enough to eat from your hand. They can't really bite you as they have no upper teeth. If you are very patient and gentle, some of them may let you pet them on the neck.
They are pretty smart for prey animals, and very social in their herd.
We had a baby (called a 'cria') a couple weeks ago. The ranch is off the beaten path in the hills of Malibu California, a bit rustic and very peaceful.
Alpaca are great jumpers. Most any of them could get out of their areas if they are motivated, but they like each other and tend to just stay in the pens. There are a few that will take the odd walk around the grounds though.
And yes, discounts and special treatments are available for those that pay in Bitcoin.
