Effect of Hatching Time on Yolk Sac Percentage and Broiler Live Performance

INTRODUCTION There has always been a natural biological variation in the time that commercial broiler chicks emerged from their egg shells (hatch time) even under optimum conditions of artificial incubation. Thus, early hatching chicks have generally remained in the hatcher longer while awaiting removal of later hatching chicks from the machine (pull time) (Elibol et al., 2011; Powell et al., ...

There are numerous factors such as egg weight, egg cooling rate, egg transport condition, egg storage duration, egg position in the machine (EST variation).
Firstly, we need to discuss your situation to solve the variation. Kind regards.
