The power has to be only off for a few minutes and the chickens die from the heat.
They're packed in like sardines, it saves money except when the power goes out.
CLEVELAND COUNTY, NC (WBTV) - Workers are trying to clean up and bury thousands of chickens who were killed during a power outage at a farm in Cleveland County.
Up to 60,000 chickens have died at Greenway Farms on McCraw Road.
Officials say the owner was using a generator connected to large fans in the chicken houses which experienced some sort of power outage.
The large fans help pull air through the building to keep the temperature down. When they're not working, if only for a few minutes, it can cause the chickens to die from the heat.
