Supplemental data for: Transient behavioral effects of feed restriction in a white feathered laying hen pullet strain: Assessment of frustration and locomotor energy expenditure

This study aimed to assess any negative welfare consequences of using quantitative feed restriction to slow the growth of laying hen pullets. Pullets were raised in furnished floor pens in a split-plot design: Two ages at photostimulation (18 weeks: early-PS vs 20 weeks: late-PS) with two feeding regimens each (ad libitum: AL vs 20%-restricted: R) between 12 and 21 weeks. Home pen video recordings were annotated for four behavioral categories: abnormal pecking, aggression, high energy aerial locomotion, low energy ramp use. Data were collected between June 2024 and August 2025.
