My Barred Plymouth Rock Bantam rooster Penguin just turned one year old. He is a very spirited rooster and he eats better than I do. He gets an egg every other day if not everyday, he gets dried meal worms, corn on the cob and in the can, seeds, cheese, grapes, peaches (the fruit picked off the tree), and many other foods. What do you expect his life expectancy would be? And how could I improve his chance of living longer?
