Stress in laying hens can result in feather pecking, a behaviour that can have severe welfare and economic consequences. E’layna and Tahlia chat with Claire Mindus, a PhD candidate in the Department of Animal Biosciences. Claire discusses her research on a promising solution to feather pecking, that involves supplementing hens with probiotic bacteria. Note: the research discussed in this episode, and all animal research at the University of Guelph, is done in adherence to the University of Guelph Animal Care Policy and Procedures.
