The average thickness of the shells from 75 unincubated coturnix quail eggs was found to be 0.193 mm. This was 7.3 percent greater than the average thickness (0.179 mm.) of the shells from 60 fully incubated eggs from the same hens. The two sets of eggs were collected simultaneously. This thickness difference was statistically significant (t-test:p< 0.005).
