Breaking the Shell: How In-Ovo Sexing is Transforming Poultry Farming

Male chick culling sits at the intersection of economics, ethics, and public perception. Andy sits down with embryologist Dr. Yuval Cinnamon to explain how sex is determined in chickens, why early identification has been so difficult, and what new biological and optical methods can do to change the story before hatch. Rather than a play-by-play, the discussion frames the problem producers need solved, the constraints hatcheries face on speed and accuracy, and the scientific paths that could scale beyond pilot projects. They talk about the long trail of research that brought today’s approaches into view, from understanding early embryonic markers to developing noninvasive screening that keeps the egg viable for high-throughput lines. Dr. Cinnamon explains how reducing unnecessary incubation aligns welfare and efficiency, how different markets view the tradeoffs, and what milestones must be met for global adoption. If you are looking for a grounded, forward-looking take on pre-hatch sexing that respects biology and the realities of modern hatcheries, this episode connects the science to the system that needs it.   CREDITS Host - Andy Vance Producer - Lyndsey Johnson Audio Editor & Engineer - Michael Lunt   LEGAL The information provided in this episode of Unplucked is for informational and educational purposes only and should not be considered professional advice.
