Once they're big enough and strong enough, the turtles will be reintroduced to their native habitats to help restore the wild population in western Illinois.

Zoo officials said the U.S. Fish & Wildlife Service provided nine clutches of eggs as part of the conservation effort. These 26 hatchlings are the last to come out of their shells.
The ornate box turtles, a "threatened" species, will stay at each zoo for several months before being released onto protected sand prairies in Savannah, Ill.
"We're thrilled to be working with the U.S. Fish & Wildlife Service and Lincoln Park Zoo on this hatch and head-start program for the Illinois state-listed 'Threatened' ornate box turtle," said Andy Snider, curator of herps and aquatics for the Chicago Zoological Society, which operates Brookfield Zoo. "Assisting in cooperative conservation projects for local species, such as this, is one of many ways zoos can contribute to the overall health and welfare of wild populations."
