That's a hobby farm. They both still work full time day jobs. She's a nurse, he's in marketing (remote work). I guess that's what HN really wants-- having it both ways.
Most small farms require a second job to make ends meet, or at least one person who can provide benefits from a "normal" job. Even if it's more than just hobby level. I know quite a few people waking up at 4am to do farm chores and then going in to a fulltime day job.
Most states have legal definition to determine if you're a farmer, like if you make more than 30% of your money from farming.
It is interesting but it is very hard work to husband animals but they seem very happy.
