There comes a time in every bull’s life where he must be separated from his cow wives to live a life of solitude in his own pen. We do this for the safety of the future calves, so that they will not be born during the harsh winter months. Calves being born in the winter hurts their chances for survival, so for a few months Wallie has to live in Wallie World. Where he will be well fed and loved on until he can rejoin his cows in a few months.
