For those of you who don't speak British Commonwealth idiomatic English, a crocodile can also mean a line of school children. The relevance of this term to the real topic of this Yarn will become clear later. (If you are one of those who read the last chapter first, skip to the video at the very end of the Yarn.) The real topic of this yarn is "Do sheep work?" More specifically, do my sheep consciously choose to cooperate in the work of the farm?
