Shining Light Into Unhatched Eggs Could Allow For Chicken 'Gender Reveals'

New Technique Offers Insight into Chicken Egg Gender

Researchers have unveiled a groundbreaking noninvasive method that utilizes light to discern the gender of unhatched chicken eggs. This innovation could play a significant role in reducing the meat industry's troubling practice of culling billions of male chicks shortly after birth. Published in the journal Newton, the study illustrates how light penetrates the shell of a bird egg, reflecting multiple times within, allowing photons to travel distances of up to 2 meters (6.6 feet) inside the egg's small 4-centimeter (1.6-inch) cavity.
