The effect of foraging material and perch height on feather pecking and feather damage in laying hens (1998)

Wechsler, B., Huber-Eicher, B.

Abstract

Feather pecking was less frequent in pens with than without polystyrene block [foraging material]. On the other hand, feather damage in week 30 was significantly more pronounced in pens with low than with high perches, but not significantly influenced by the provision of foraging material. .. If straw is provided as foraging material, special attention should be paid to its form, as long-cut straw is more efficient in reducing feather pecking than straw in shredded form. .. Hens sitting or standing on the floor were especially likely to elicit feather pecking. .. It is concluded that hens should be provided with foraging material and high perches during the laying period to reduce feather pecking and feather damage.
