yes all adult birds are loose in the large flight pen. Separate them by Feb. or mid March at the least. they start laying in May. Note the pens on the right side each with small building, young bird pens. Yes they can come out in the weathers, they are placed in these pens at 3 months old.
No light for increased daylight, think that would mess up the peacocks molt. The flight pen is 14 ft hight and if i remember right. barn is 40ft by 50ft, 14 ft high side walls.
