Scharmann, W., Oester, H., Blokhuis, H. J. et al.
Abstract
Berlin Workshop' recommendations for the adequate housing of laying hens address the following issues: (1) Should laying hens be kept in pens or in cages? (2) Should laying hens be kept in groups or individually? If in groups, what should be the group size? (3) What should be the minimum size of pens and cages? (4) What construction and design of the floors of the pens or cages should be used? (5) What structural division of the space should be available? (6) Is bedding necessary? If so, of what quality? (7) Do the described housing system provide hens with the opportunity of taking sufficient exercise? (8) Should occupational or nesting materials ( enrichment ) be supplied?
