Eggs in Quantity (image) Duke University Share Print E-Mail Caption A new study of egg patterning is based on a collection created by retired British Maj. John F.R. Colebrook-Robjent on his ranch in the Choma district of Southern Zambia over a 35-year period. He painstakingly drilled and blew out each of the tiny eggs, and marked them with a set number to indicate which ones belonged in the same clutch.
