A tractor track smashed all but 1 of the eggs on the next round. 19 I found the remains of a f about 5 feet from her nest, which contained 6 eggs. 3 eggs were intact, 2 were broken, + 1 was cracked. The young in the eggs had downy feathers already developed. June 19 The f had deserted this nest. The 5 2 eggs were still in the nest, but they were cold. The embryos were just beginning to form. 20 A nest with 5 eggs that had been eaten was found in the grass along a ditch bank. 3 The eggs in this nest had hatched, leaving no eggs intact - apparently all had hatched. 7 This nest was uncovered by a "push-header" harvester yesterday afternoon. about 12:30 P.M. today I flushed the f from the nest, which contained 4 eggs 4 was undamaged by the harvester.
