The influence of turning on the hatchability of hens' eggs I. The effect of rate of turning on hatchability

The Journal of Agricultural Science, 1961
Eggs were incubated at various frequencies of turning (tilting through 90°) and their hatchability compared with eggs incubated as controls at 24 turns per day evenly distributed throughout the 24 hr. The turning treatments were: 0, once in 2 days, 2, 6, 12, 48, 96, 144, 192 and 480 turns per day.Differences in hatch of fertile eggs between the treated
