STICKING TOGETHER Emperor penguin dads are very hands-on. When in winter, the mums have laid their eggs and headed out to sea to feed, she leaves the egg in the custody of the father who will not eat, drink or move for those two months. Broods of dads huddle together and keep the eggs warm. In fact, if the chick hatches before mum’s back, dad can produce milk to feed the baby.
