A device for processing slaughter animals or parts thereof, for example poultry, comprises a transport system with an endless track and a chain of chain elements which can be moved along the track, wherein a plurality of chain elements are set up as carriers to carry one or more slaughter animals and/or parts thereof. The device furthermore has a delivery station for delivering slaughter animals or parts thereof to the carriers of the transport system, one or more stations being set up along the track of the transport system to perform actions relating to the slaughter animals or parts thereof. The device furthermore has location means for determining the position of the chain in relation to the track, wherein the location means comprise an identifiable chain element which has an associated identification mark, and also an identification sensor set up along the track to detect each identifiable chain element, wherein the remaining chain elements in the chain are designed as unidentifiable chain elements. The location means furthermore comprise a counting device to count the unidentifiable chain elements which pass along a counting station by the track following the passage of an identifiable chain element. Moreover, the location means furthermore comprise electronic memory means with a memory table in which a memory field is provided for each carrier, wherein the location means record a variable in the memory field representing the number of carriers counted by the counting device since the passage of the identifiable chain element located upstream.
