NBC Bird flu is spreading again as water fowl migrate. In poultry, cases are spiking earlier than expected, so some state officials are bracing for a challenging autumn. It was a quiet summer for bird flu: Egg prices fell a bit, fewer sick poultry flocks were culled on farms, and officials took a breath.

But it didn’t last.
Bird flu is spreading again, now that wild water fowl — geese, ducks and cranes — have begun their seasonal migrations. As the birds travel, they mingle at lakes and ponds and share viruses.
