Temporal Variations of Air Quality in Cage-Free Experimental Pullet Houses

Poultry, 2023
The welfare of laying hens in conventional caged houses has become an increased public concern, leading primary food chains, restaurants, and grocers in the United States to pledge to source only cage-free (CF) eggs by 2025 or 2030. Cage-free housing systems have been considered as a more humane alternative; however, they still come with certain ...
