I've been doing the terrier work on abig pheasant shoot for years keepers a great bloke,last season his neighbour asked me to do some for him only small farm about 250 acres I noticed he had quite alot of feeders but no pens, couple of months later was talking to keeper said his neighbour had let me go on his farm,well to say he hated the farmer was a understatement he definitely wanted to kill him,I said I would not go again,6000 acres his far better than 250.
