By Leonie Jacobs - Tessa Grebey and colleagues researched dustbathing behavior in a range of commercial laying hen breeds, including Hy-Line Brown, Bovan Brown, DeKalb White, and Hy-Line birds.
They found that strains respond to social situations differently.
These findings are important considerations for egg producers, and support other work that show that not all breeds or strains of laying hens are the same. When designing housing, and when choosing birds, people need to consider strain differences.
