Millions of egg-laying hens needlessly suffer from painful bone fractures, osteoporosis, and elevated mortality rates due to suboptimal feed standards. Hens are now producing 10 times as many eggs as they were naturally born to do, and this forced increase of production weighs heavily on their well-being by depleting their bodies of key nutrients, including calcium, phosphorous, and vitamin D. By ensuring that an optimal level of these nutrients are supplied via feed, we can cost-effectively reduce the suffering of >72 million hens (over 10 years) and allow them to express their natural behaviors via improved welfare. As recent studies have shown, this neglected issue occurs not only in battery cages but also in cage-free systems (the preferred housing system), so we must act now to achieve unprecedented counterfactual impact and more healthier hens.
