LA GRANGE, WI (AP) -

Authorities are investigating a fire that went to four alarms at a large southeastern Wisconsin egg farm.

The fire was reported at the S&R Egg Farm in La Grange in Walworth County around 7:45 p.m. Friday. According to the company's website, it's a third-generation, family-owned business founded in 1958. The company says it produces up to 2 million of Wisconsin's eggs and distributes them across the country.

WISN-TV reports an estimated 300,000 chickens were housed in the barn that burned.  Firefighters say firewalls helped protect other buildings.
   A damage estimate was not immediately available. Farm officials said they were preparing a statement Saturday.
