[Assessment of furnished cages for laying hens--development for small aviaries].
Observations on six farms keeping laying hens in furnished cages showed that hens accepted the installations of this new housing type. Behaviours indicating that the adaptations of hens were problematic have not been observed. Locomotion and dust bathing in some groups occured as not sufficient. Lighting was too low and affected expressions of behaviour patterns. For further developments are proposed more usable space per bird and a different placement of perches. Dust bathes should be utilized permanently and should contain sufficient amount of litter.
