the borchester land history that zero linked to above has some details about the home farm / BL relationship:
" Arable contract
Brian had negotiated a five-year contract to farm the ‘in-hand land’. Brian’s step-daughter Debbie Aldridge would manage the contract from Hungary while his step-son Adam Macy would carry out the work. But by 2001, he was sweating, as the Estate had not delivered the farming income he had projected. Unsympathetic to Brian’s excuses of a market slump, rising fuel costs and poor weather, the board appointed new contractors. It was 2006 before Home Farm won the contract back.
...
The ‘mega dairy’
The market was a walk in the park compared with Brian’s next scheme. In September 2011, Debbie proposed setting up a large-scale dairy operation. 1500 cattle would be kept permanently indoors, and their slurry would feed an anaerobic digester supplying power to the grid.
Brian put the plans to the board. But when Adam learned of them, he refused to cooperate, as it was anathema to his philosophy of farming. Brian was forced to tread a difficult path, contracting other farmers to supply feed and silage for the cattle.
Meanwhile, public anger quickly grew. Many people were disgusted at the prospect of cows who would never see daylight or fresh grass. Brian was at odds with members of his extended family. BL countered a difficult public meeting, rowdy demonstrations at their market and critical press coverage with a PR campaign and a glossy DVD.
In April 2012 the council approved the application. But it still wasn’t plain sailing. When one of the contracted farmers pulled out, Brian unilaterally decided that Home Farm would have to step in. Adam came close to throwing it all up and moving away but he and Brian eventually reached a shaky détente.
Building work began in September. In January 2013, highly qualified Rob Titchener started as herd manager, and the first heifers arrived in August. In a bid to belie the vast industrial nature of the buildings, Brian and Rob named the enterprise Berrow Farm, to the scorn of its critics."
