I'm pretty sure Herm doesn't have a brother who is a chicken. I believe he meant "poultry in motion."
David had an expensive Mynah bird he got for his birthday. The bird had a bad attitude and even worse vocabulary. Every other word was an obscenity. David tried very hard to change the bird’s behaviour but the bird refused to cooperate. David tried very polite language and tried to set a good example, but the Mynah was obdurate. Finally David lost his temper, shook the bird and then shut it in the freezer. From outside he could hear the bird swearing, kicking, shrieking and squawking. Then everything went quiet. David was scared that he might have hurt the expensive Mynah bird. He opened the freezer door and the bird calmly walked out and said, “I am extremely sorry that I might have offended you or caused you discomfort with my language and choice of expressions.

WHY DID THE CHICKEN CROSS THE ROAD? Plato: For the greater good. Nietzsche: Because if you gaze too long across the Road, the Road gazes also across you. Carl Jung: The confluence of events in the cultural gestalt necessitated that individual chickens cross roads at this historical juncture, and therefore synchronicitously brought such occurrences into being. Albert Einstein: Whether the chicken crossed the road or the road crossed the chicken depends upon your frame of reference. Buddha: If you ask this question, you deny your own chicken-nature. Ernest Hemingway: To die. In the rain. Chaucer: So priketh hem nature in hir corages.
