See four of these critically endangered birds hatch out of their shells at the Houston Zoo - there are fewer than 100 Attwater's Prairie Chickens left in the wild, so each time a chick hatches, it is a critical contribution to the species' survival. Check out http://www.houstonzoo.org/prairiechicken to see the great work the Zoo is doing to save these animals!
