The development of laying hen locomotion in 3D space is affected by early environmental complexity and genetic strain.

Abstract in brief

• The study found that early environmental complexity (such as different housing conditions) influences the spatial skills of young laying hens, with white feathered hens generally performing better than brown ones regardless of their environment.
• White hens from more complex aviary environments showed the greatest improvement in spatial tasks compared to those from simpler settings, while brown hens' performance was less affected by early environment.
• The research suggests that exposure to varied vertical structures during early development enhances hens' ability to navigate complex spaces, especially in white feathered hens, highlighting the importance of environmental enrichment.
