Bird flu gone for a year, but mystery remains

The barns at the Pullet Connection chicken farm are nearly full of young birds again, a big change from last June. That's when avian flu struck the operation near Redwood Falls. The family farm saw more than 400,000 birds destroyed and the barns — normally teeming with cheeping, fuzzy chicks — fell silent.

"The process was so difficult to go through that you never want to do it again," said Barb Frank, Pullet Connection co-owner.
