Mrs Brown wants to teach me about the Chicken Calendar, a Calendar that has no Dates as chickens can only think 4 weeks at a time. "All you need to know is what to do each week", she says, "and do it again 4 weeks later, over and over again until you know the routine and it becomes automatic, part of your nature." "I'll tell you more tomorrow, its dusk and I need to go to sleep..........." Goodnight, Mrs Brown.
