Millions of chicken species including the greater prairie chickens lived on the grasslands of Illinois. This land was converted to farmland and used as a source of food in the 19th and 20th centuries. By 1993, the island lost the large areas of grassland. As a result, most chicken species disappeared and the number of greater prairie chickens dropped as fewer than 50 birds were maintained.
