The fire was reported around 7:45 p.m. Friday at the S&R Egg Farm in La Grange in Walworth County. The company said in a statement Saturday that one of its 14 barns at the site was a total loss, but no people were injured.
An estimated 300,000 chickens were housed in the barn, WISN-TV reported. Firefighters said firewalls helped protect other buildings.
The company statement did not provide a damage estimate or say how many chickens were killed, and CEO Dan Gorecki did not immediately return a call seeking details.
The company said it plans to rebuild the barn and that all its other barns remain in full production. There was no damage to the company offices or its egg processing and packaging facilities and no chemicals were involved in the fire, the statement said. The statement said no further information will be released until the investigation is finished.
S&R Egg Farm is a third-generation, family-owned business founded in 1958. The company's website says it produces up to 2 million eggs a year and distributes them across the country.
