Captain Joseph Cassatt of the Heidlersburg Fire Company said flames were visible above the roof of the 600-foot barn by the time fire crews arrived.

Crews concentrated on keeping the blaze from spreading to other buildings. Three firefighters were treated at the scene, two for dehydration and one for a laceration.

Fire Chief Dwayne Keene said adjacent chicken houses were undamaged and the animals unharmed. Keene said the burned building was a total loss.

Officials said the cause of the fire is still under investigation but it is believed to have been accidental.
