An egg conveyor is used to convey eggs (11), in particular in larger egg-laying facilities. In the case of an egg conveyor with a longer conveying path, the conveyor chain (21) which can be driven circumferentially along the conveying path (10) is subject to high loads. In order to keep the load of the conveyor chain (21) within limits in the case of a longer conveying path, an intermediate drive (28) is provided in addition to the main drive (27). The driving force is thus introduced into the conveyor chain at different positions, so that it is subject to less load. This also leads to a smoother driving of the egg conveyor. Preferably, in the area of ​​the intermediate drive, the conveyor chain in the area of ​​the upper branch is guided along an arc-shaped bulge. This results in a more favorable overlap coefficient between the conveyor chain and the drive gear driving the conveyor chain. The intermediate drive can be converted into a conveyor chain in the area of ​​the upper branch or the lower branch, which can be selectively driven. The intermediate drive can therefore be used more widely.
