The M62 has closed after a lorry crashed and spilled dozens of chickens onto the road.
The caged birds were flung across the motorway during the collision near the Eccles Interchange in the early hours.
About 1,500 birds were killed, North West Motorway Police said.
One lane on the eastbound carriageway remained closed between junction 11 (Birchwood) and junction 12 (M60 Eccles Interchange) while emergency crews cleared the crates and other debris from the road.
Diversions are in place but motorists are facing long delays and are advised to avoid the area.
The lorry was carrying in total 6,000 chickens when it hit the safety barrier at 4am.
