Enterprising Students A select group of "investors" recently began a new venture at the Ranch-- Wears Valley Chicken Corporation. It's only a corporation on paper, but the life lessons are real.    For a small initial investment of five Ranchbucks, our student investors are learning about gross revenue, expenses, net income, supply and demand, and more. As shareholders they are also responsible to care for the chickens, so their diligence directly affects their profit. Along the way, we hope they will learn other lessons about nutrition and marketing as well.    Many thanks to Chef Kam for overseeing their work and providing a rich learning (and eating) experience!
