Federal figures show H5N1 avian influenza infected about 1.32 million US birds over the past month, led by a roughly 934,600-bird chicken outbreak in Clinton County, Illinois. Additional outbreaks hit turkey and chicken operations in Minnesota, Wisconsin and North Dakota.
Losses of laying hens and meat birds reduce poultry supply and raise egg prices, while lower chicken output can shift demand toward other proteins. The effect on feed demand is modest, but ongoing outbreaks add to supply tightness for poultry.
