By incubating eggs at the optimal eggshell temperature of 37.8ºC but with variable RH, effects on embryonic mortality, chick quality and development can be attributed to RH and water loss. Therefore, this study was performed to determine embryonic mortality, chick quality and postnatal development of chickens from eggs incubated at a high or low RH while maintaining the eggshell temperature at 37.8ºC throughout incubation.
