A flock of young turkeys stand in a barn at the Moline family turkey farm after the Mason, Iowa farm was restocked on Aug.  10, 2015. Farms that raise turkeys and chickens for meat and eggs are on high alert, fearing a repeat of a widespread bird flu outbreak in 2015 that killed 50 million birds across 15 states and cost the federal government nearly $1 billion.  The new fear is driven by the discovery announced Feb.  9, 2022, of the virus infecting a commercial turkey flock in Indiana.
