Recent US bird flu outbreaks, including a 934,600-bird outbreak in Illinois on October 19 and a roughly 1.3 million laying hen outbreak in California on October 28, are raising concerns about egg and chicken supply ahead of the holiday season. A new outbreak was also reported on a Dutch poultry farm at the start of the 2026/27 season.
Losses of laying hens tighten egg supply and can lift feed demand for layers, while poultry disease adds risk to chicken supply. Egg prices are currently easing nationally, so the price impact is uncertain.
