Quick facts
- Free-range broilers with less outdoor space may sunbathe, aggressively attack, stretch, or pant more than those with more outdoor space.
- Extra outdoor space may slightly improve broiler welfare, but the quality of outdoor space is likely more important than its size.
- Free-range broilers should have access to shade structures and an ample amount of forage cover.
Outdoor access for free-range broilers
Free-range broilers require outdoor access. Many believe that more outdoor space improves broiler welfare, but there is little research to support this idea. Therefore, in our study, published in the journal Animals, we evaluated if the amount of outdoor space affects broiler welfare.How we conducted the study
In this study, we raised Freedom-Ranger broilers at high (5 sq. ft. per broiler) and low (27 sq. ft. per broiler) outdoor stocking densities. We evaluated behaviors and feather damage from 5 to 11 weeks of age.View of high (left) and low (right) outdoor stocking densities. The two groups had a covered mobile shelter of equal size.
Means (± 95% CI) for 10 behaviors averaged over 5 to 11 weeks of age. Diverse behaviors were observed at both outdoor stocking densities.
