I have a smallholding myself mate and there is no way it would make money, it can feed me which is worth about 10k a year but it will still be a cost.
Shame but it's not just small boys, it's big farms too.
I travel from South Wales to the midlands quite regular and have noticed a lot more honesty boxes outside people's homes.along with eggs there's quail eggs fruit and veg even jars of chutney and pickled cabbage etc.
