TI  - How should a hen run be structured so that it is used evenly by laying hens ?
Y1  - 2004///
N2  - The aim of this study was to obtain an even use of the hen run with structures as an uneven use leads to a nutrient and heavy metal overload on the frequently used areas. In particular, we looked at the preference of hens for a certain kind and amount of structuring elements.
