Storage of hatching eggs is a common procedure at breeder farms and hatcheries. Previous trials showed that a warming profile at the start of incubation, of which the increase in temperature from 29.4°C to 37.8°C was controlled, reduced early embryonic mortality in long stored eggs (>7 days) in comparison to no controlled warming profile. The current trial investigated the effect of warming profile on hatchability and chick quality for short stored eggs (< 7 days) of a young, prime, and old flock.
