The baby African penguin emerged from its shell at the Pueblo Zoo on March 20, but it was four days overdue and needed help from a staff worker to get out.
When the biological parents appeared unable to care for the hatchling, it was taken to Denver and placed with surrogate parents, who immediately began to feed it and keep it warm.
African penguins once came close to extinction and are listed as "vulnerable" by the International Union for the Conservation of Nature and Natural Resources.
