Chickens from the outdoor access groups had a better appearance and degree of evenness. Birds in the outdoor access groups had a significantly lower lung percentage than birds in the control group (P < 0.05), whereas the kidney percentage of the 35-d group was significantly lower than that of the control group (P < 0.05). The meat of chickens in the
35-d group had higher L* values than that of the control group (P < 0.05). Compared with rearing indoors, outdoor access significantly increased the shear force of the breast muscle in both the 35 d and 70-d group (P
