I would shut them in, but use a screened floor, rather than a screened top,
and I would also put a cover over to keep them as dark as possible without
restricting airflow. An open screened top will result in many bees trying
to fly up through it towards the light and with a strong hive they could
block the screen and suffocate the hive. Give plenty of water.
