This questionnaire\u2010based study explored correlations between disease, housing, management practices and smothering on free\u2010range farms. A binomial logistic regression approach was used to test whether question responses predicted occurrence of nest box smothers (NBS) and panic and recurring smothers (PSRS) on farms. Breed (P=0.008) and nest box manufacturer (P=0.014) predicted NBS. Breed and nest box design have been previously reported to affect nesting behaviour. The affect of nest box manufacturer found in this study may illustrate the effect of nest box design features or house layouts. Nest box manufacturer (P=0.009), feeding oyster grit or grain on the litter (P&lt;0.001) and range use on a sunny day (P&lt;0.001) also predicted PSRS. Implementing some management practices to encourage desirable behaviours (eg ranging) may contribute to smothering, whereas some management practices such as those aimed at occupying birds may be beneficial, illustrating the delicate balance of factors involved in free\u2010range egg production. It is hoped that these results will stimulate further work exploring the suitability of housing design and management of laying hens in light of smothering.<\/jats:p>","DOI":"10.1136\/vr.103701","type":"journal-article","created":{"date-parts":[[2016,6,29]],"date-time":"2016-06-29T00:36:18Z","timestamp":1467160578000},"page":"252-252","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":19,"title":["Smothering in UK free\u2010range flocks.
