(Undated)  --  A Minnesota chicken hatchery is being investigated by federal officials to see if there is a possible connection to the recent Salmonella outbreak involving eggs.  Two Iowa egg producers have recalled millions of eggs and both were supplied chicks from Minnesota.  Dr. Chris Braden of the Centers for Disease Control and Prevention (CDC) says more cases of Salmonella are likely to be reported in the days to come.  So far, 14 Minnesotan's have become ill after eating tainted eggs.
