Clackamas Fire was sent to a residential fire just after 11:30 a.m. in the 16300 block of Southeast Bel Air Drive in Damascus.

When firefighters arrived, they found a 20x20 outbuilding that housed chickens on fire.

Officials say the fire also spread to a small greenhouse and believe an electrical issue caused the fire.

A Clackamas Fire spokesperson said 20 chickens were lost in the fire. No human injuries were reported.
