Watch a Whooping Crane Hatch! Video Viewing Tips Macs PCs Film clip Operation Migration Whooping Cranes Hatching! These whooping crane eggs show how life started for a very special group of chicks. In a bold migration experiment starting in 2001, whooping cranes have been raised in captivity and reintroduced, or brought back, to eastern North America. The whooping crane eggs for this project hatch in April and May at Patuxent Wildlife Research Center near Laurel, Maryland. The chicks in these eggs will take off in 6-7 months on their first migration. Becasue they doon't have parents, an ultralight airplane teach them the way! An average whooping crane egg is 102 mm (4 inches) long. It weighs 208 grams (7 ounces). Whooping crane eggs are incubated, on average, for 30 days. Try This!
