<p>Free-range laying production system supplies 52% of the national egg demand (Australian Eggs 2021). Hens in this production system show a broad spectrum of behaviours. Some hens spent 77-80% of their time on the outdoor range while stayer hens spent less than 20% of their time on the outdoor range (Sibanda <i>et al</i>. 2020a). It is still unclear if the differences in range use, which is associated with egg production, is the cause or consequence of a diverse phenotypic and intestinal microbiota composition. Very little is known about the intestinal microbiota of free-range laying hens to date. A better understanding of the microbiota composition may help to establish better management strategies. Therefore, the aim of this study was to describe the intestinal microbiota of commercial free-range laying hens with divergent body weight and range use.</p>
