D.M. Karcher studies the health, welfare, and housing of egg-laying hens, with particular focus on how different housing systems (cage-free, enriched colony cages, aviaries) affect Salmonella contamination, bone injuries, and bird behavior. Much of the work involves experimentally infecting hens with Salmonella to track how the bacteria spread through their organs, eggs, and the surrounding environment, as well as examining how housing design contributes to physical injuries like keel bone damage. This research is aimed at improving commercial egg production practices and food safety.
