Unlike standard battery cages, aviary and perchery systems offer laying hens a more complex environment and allow them to move in a three-dimensional space. Eighty Lohmann layer hens were reared in floor pens fitted with perches from 1 day of age to observe the accuracy of jumping of hens from and to the perches. After the peak of lay (25 weeks of age), their ability to jump to and from perches in different light environments was assessed in two experiments. Results of this study show that birds show behaviours indicating accurate control of landing where it was more frequent on downward than upward jumps. However, these behaviours were not affected by light intensity, light type or contrast. In conclusion, the results of this study suggest that there is a difference between the two types jumps in the risk of injury to hens housed in aviaries where perches must be used to gain access to resources.
