Abstract: This research aimed to compare locomotion and musculoskeletal characteristics of white- and brown-feathered strains of pullets reared in three different styles of commercial rearing aviaries. Aviaries were categorized into three styles based on the vertical and horizontal space available during the brooding period. Pullets in the style with the most space during the brooding spent the most time locomoting throughout rearing. Differences in higher intensity behaviours such as running, wing-assisted running, and group locomotion were most evident during the brooding period. These pullets, as well as white-feathered strains, performed the most vertical transitions and had the strongest leg bones. White-feathered strains had proportionally heavier pectoral muscles, lighter leg muscles, and larger keels than brown-feathered strains. These results indicate that style of rearing aviary and strain of pullet affected their locomotion and musculoskeletal characteristics which may impact their long-term success in an adult aviary.
