Industrial processes follow a clear, linear, hierarchical logic that is fairly easy to put into words, probably because words follow a similar logic: First this, then that; put this in here, and then out comes that. But the relationship between cows and chickens on this farm (leaving aside for the moment the other creatures and relationships present here) takes the form of a loop rather than a line, and that makes it hard to know where to start, or how to distinguish between causes and effects, subjects and objects.
