Fletcher Adam and brothers Alex and Isaac Seaton have started out small, but who knows how quickly their business will grow.
The Sawyers Bay trio set up a roadside stall in Stevenson Ave yesterday, selling homegrown potted succulents, an apple sapling, flaxes and kanuka.
Isaac said they planned to use the money raised from their sales to buy chicken feed for their seven hens, which provided eggs.
And you guessed it, they sell the eggs, too.
"They lay one egg a day, and we sell them to anybody that drives past.
"It's $7 per dozen."
Asked what that money was going towards, Alex said they were saving some of it for their futures.
"For stuff like university fees and things we might need in the future, like a house or a phone," Isaac said.
And the rest of the money was being divided between them to spend on whatever they wanted.
Because their income was still relatively low, their business acumen was pushing them towards buying more chickens and more chicken food.
"More chickens means more money," Alex said.
"We're going to expand the business so we can make even more money.
"Could you help us with advertising, please?"
The boys said they still had more homegrown plants ready to be sold and their stall would be open until the end of the school holidays.
After that, they would be open after school, most days.
Despite their young age, the trio did not have any ambitions to be big-name billionaires like Donald Trump or Elon Musk.
"I feel like we're just going to do the business, like, maybe until we're ... out of school. And then we might get better jobs," Fletcher said.
"I'd rather be an astronaut — like Neil Armstrong."
