Abstract
The fresh weight of silver gull eggs is closely related to the volume, which is calculable from the length and breadth. Since eggs lose weight at a constant rate during incubation, the density (weight/volume) indicates the duration of incubation. Accuracy of the method was ± 2 days in 217 of 250 tests. A curve of age against density is provided
