The charred remains of the 600-foot-long chicken house on the property of A & L Farms were still smoking this afternoon.
The owner of the farm tells Action News that along with tens of thousands of laying hens being killed, several million dollars worth of damage was done.
The fire broke out right around 7 p.m. Tuesday on the 3300 block of Mountain Road.

State police say the fire started in the east end of the building, and by the time firefighters arrived the roof had collapsed.
Flames were shooting high into the air and the plumes of smoke could be seen for miles around.
Officials from the Fire Marshal's office say they will not be able to fully and safely investigate the scene until lingering hot spots and smoke subside.
