Egg Corp Assured is the weakest standard, set by the industry peak group and largely based on the Model Code of Practice. Egg Corp Assured differs in that it interprets the outdoor stocking density figure as largely irrelevant to welfare. Egg Corp Assured has been known to certify farms running up to 44,000 birds per hectare outdoors, far in excess of recommendations. Like the Model Code of practice, beak trimming is allowed and indoor densities run up to 15 birds per m2.
