About 2,000 chickens have died in a truck fire on Adelaide's South Eastern Freeway.
About 30 fire crews worked to extinguish the blaze, which happened on the down track between Mount Barker and Hahndorf just before 4:30am.
The driver escaped unharmed and the remaining 2,000 live chickens were moved to another vehicle.

Both lanes of the citybound track were closed until 9:00am.
Car traffic was diverted through Hahndorf at Mount Barker, while trucks and buses continued to get through on the freeway.
"It pretty well destroyed the truck and unfortunately half the chickens perished in the fire but also it's causing long delays for Adelaide-bound traffic," SA Police Senior Constable Mick Abbott said.
The RSPCA is on the scene.
Separately, a car has rolled on South Road at Regency Park in Adelaide's inner-north.
It happened on the southbound track near the golf course just after 6:00am.
Senior Constable Abbott said drivers should use another route.
"It's causing really long delays," he said.
ABC Radio Adelaide listener Andrew was detoured through Hahndorf on his way from his home in the Adelaide Hills and then caught in the "massive hold-up" at Regency Park.
"It's a massive parking lot," he said.
