Translation:They are working on a farm in Great Britain.
It's very common to use just "gård" to refer to a "bondegård", so when referring to a traditional farm they're synonymous.
However, "gård" is a word with a wide variety of definitions, and can be used to refer to a yard of any size, and even to some types of apartment buildings. "Gård" is also used in a myriad of compounds, for example "vingård" translates to "vineyard" and "kirkegård" to "churchyard".
