Healthier Hens is a new Effective Altruism aligned animal welfare organization. Our vision is to cost-effectively improve the well-being of millions of farmed egg-laying hens. We are investigating the potential of an intervention focused on alleviating pain and improving hen health and welfare by optimizing the nutritional quality of layer hen feed, as recommended by the Charity Entrepreneurship research team. Our end goal is to lobby for legislation that sets minimum standards for nutrients in poultry feed and help enforce those standards nationwide.
