The aim of this study was to evaluate the shelf life brown eggs from laying hens different ages in an organic production system. A total 192 were used, t experimental design a factorial scheme, with four (40, 50, 60, 70, weeks) and storage periods (0, 14, 28 42 days) 12 repetitions each. Chicken age period (p <0.05) interfered egg weight loss. Eggs older showed superior internal quality first days storage, but high susceptibility losses when stored for up days. Young (up 40 weeks age) better...
