The hypothesis was that increased distance between resources and stimulation of foraging behavior would improve physical activity of broiler chickens, even though the degree of environmental complexity was altered with the use of moving lights and scattered whole wheat in the litter. It was also thought that leg condition and performance would improve, and level of fearfulness would decrease with increased activity. One-day old males in groups of 45 were allocated to one of four treatments: 1) the barrier treatment, containing three barriers placed between the drinker line and the feeder, 2) the light treatment, consisting of brightly colored moving lights projected on the pen floor for four 1-hour periods per day throughout rearing, 3) the wheat treatment, in which wheat was dispersed on the floor from days 8 to 17 and 4) the control treatment, in which the birds were maintained under standard management. Mortality, body weight, feed conversion, and the duration of tonic immobility did not differ significantly among birds in any of the treatments. Fluctuating asymmetry, bone ash, tibial dyschondroplasia and bone breaking strength, which are all measures of bone quality, did not differ among birds in any of the treatments either. Higher gait scores, which are indicative of the presence or degree of lameness a bird is experiencing, were higher among birds in the light treatment than birds in the control and barrier treatments. Birds in the wheat treatment had higher gait scores than birds in the control treatment. The diameter of the tibia diaphysis was significantly increased with the provision of barriers, which is a promising result for further studies to improve leg condition.
