Hi Leona and welcome to TAS - I'm sure you'll get plenty of good advice here to help you get started.
Whereabouts in Cambs are you?
We run a community farm just north of Cambridge with pigs, goats, chickens ducks, geese, turkeys and bees as well as doing veg boxes. I've had a bit of interest from the two schools in our village about coming out for farm visits so would love to pick your brains on what we would need to provide to make this happen.
