Chronic stress measurably reduces egg quality. These studies examine how housing density, cortisol levels and environment affect what ends up in your egg.
3 Studies
Hens in low-density, open-run housing showed significantly lower corticosterone levels across all measurement timepoints in the study.
Elevated chronic stress was correlated with reduced yolk quality, shell thickness, and omega-3 fatty acid content across all operations studied.
Overcrowding-induced social stress reduced egg production rates and measurably impacted protein and vitamin profiles in laid eggs.
