Gracie Anderson

 Research Interests

Gracie's research focuses on laying hen welfare and investigating how housing design can improve hen welfare. More specifically, determining the effect of environmental enrichment on pullet behavior, fear, and anxiety. Additional areas of interest include: effectiveness of differing perch designs on pullet behavior and activity, location preferences for environmental enrichments, developing species-specific cognitive bias tests, and determining animal affective state following manipulation of environmental conditions.
