From Wiki. Marie Antoinette's Le Hameau. It seems
'Marie Antoinette also managed the estate by overseeing various works, correcting or approving plans, and talking with the head farmer and laborers. In addition to the head farmer Valy Bussard, Marie Antoinette hired a team of gardeners, a rat-catcher, a mole-catcher, two herds-men, and various servants to work on the estate.
In spite of its idyllic appearance, the hamlet was a real farm, fully managed by a farmer appointed by the queen, with its vineyards, fields, orchards and vegetable gardens producing fruit and vegetables consumed at the royal table. Animals from Switzerland, according to the instructions of the queen, were raised on the farm. For this reason the place was often called "the Swiss hamlet".'
My take is that MA (of all people) had more of a clue about actually running something than erm some later Royals.
