A new in ovo sexing technique with a modified genetic trait to hatch only female chicks may someday help eliminate the culling of day-old male chicks. According to developer and embryologist Yuval Cinnamon, PhD, the genetically based solution offers many benefits over the other technologies currently on the market.

Beak trimming is common in the management of laying hens, involving the removal of a portion of a bird’s beak to minimize harmful behaviors. While beak trimming helps reduce injuries among birds, the technique has also raised animal welfare concerns. Thus, farmers and researchers are continuing to explore ways to manage hens without the need to trim their beaks.

Coccidiosis doesn’t just lurk in poultry houses — it thrives there. For decades, producers have relied on synthetic anticoccidials and ionophores to keep it in check. But with growing resistance and increasing pressure to reduce antibiotic use, more operations are turning to vaccination as a sustainable, effective alternative.
