@Tuxman: Each bird cooks separately. So it is like cooking one 15 lb bird. Start at same time. If one is bigger, it will take longer than the other. Allow max space between them. Put a digital probe deep in the thigh of the smaller one (avoid contact with bone), and take out when it gets to 165 take it out. Put probe in larger one, into thigh, take out when it gets to 165.
