Might we ask how large your sheep farm is, by current commercial (vs. hobby) standards?

I'm not a farmer so I can't speak to how much of this is unreproducible, but it does seem very interesting. The paper pot transplanter blew my mind.
The title says they make $13k per week, which would be $676k... so $13k must be just during the weeks they produce. And it seems to be based on the grocery-store price of that food, rather than the actual wholesale price that they're able to sell it for.
I wanted to watch at least enough to understand how the title is misleading. If two people could make $13k/week on an acre there would be a hell of a lot more people doing it.
It's still cool though, they've clearly worked hard and made great use of their land.
