Abstract

The aim of this study was to reduce feather pecking in layer chickens kept in isolators for research purposes by inclusion of bunches of string and/or a sand box in a 49 day experiment in non beak trimmed SPF White Leghorn chickens. Inclusion of string from day 0 significantly reduced the incidence of feather pecking and kin injury and significantly improved (P<0.001) feather coverage and feather feather condition score. Inclusion of a sand box from day 14 onwards did not significantly affect these variables although there was a trend for improvement in each case, particularly when combined with thepresence of string. The inclusion of a sand box at day 0 warrants further investigation. We have shown that simple environmental enrichment within isolators can lead to a significant reduction in feather pecking behaviour and now routinely include string in our experiments.
