> The results from several studies suggest higher levels of mortality in cage-free systems compared to battery cages and there is reason to believe that higher levels of mortality correspond to lower levels of welfare since the increased mortality may result from disease, feather pecking, and injuries. Among the nine experts interviewed in The Open Philanthropy Project’s report “How Will Hen Welfare be Impacted by the Transition to Cage-Free Housing?” there was unanimous agreement that mortality will likely be significantly higher following the transition to cage-free systems. The authors of the report express optimism that producers will be motivated to and capable of reducing mortality levels to be comparable with battery cages and maintain the view that cage-free systems will have a net positive impact on welfare in the long term.
