Some Factors Affecting Hatchability of Chicken Eggs

Hatchability of White Rock eggs was found to be significantly (p <0.05) affected by storage period and incubation position but not by storage position. However, there was a tendency for eggs stored with the small-end-up to hatch better than those with the small-end-up or small-end-horizontal. Maximum hatchability was obtained by combining a four-day to a six-day storage period with the small-end-down incubation position. There was no significant (p >0.05) interaction between storage period, storage position and incubation position.
