yes all year it's called roundabout, when the cocks are out flying the hens are locked into the sections with the boxes, when the cocks come in they trap into the corridor and are ushered into a section on the end of the shed were the hens are normally kept. then the hens go out and the cocks are brought back into the sections were the boxes are, and are locked in, when the hens come in they trap back into the corridor and are ushered into the section on the end of the shed.
