Abstract
A novel method for determining air cell location, embryo development, and eggshell defects in opaque thick-shelled eggs was tested. Results demonstrated that a camcorder with IR “Night Shot” function performed significantly better (P < 0.05) than unaided visual determination of air cell location in Emu eggs. In addition, the Mini DVC camcorder unit was as accurate as the heavier, non-portable, and more expensive traditional IR candling units. Commercial ratite producers, waterfowl biologists, and others working with opaque thick-shelled eggs may benefit from this research.
