If this was a package, no drone brood is expected. Packages starting out have no use for drones. You should decide what you need for a brood chamber. One deep. two deep, a deep and a medium, ETC. Once that brood chamber is mostly filled out and covered in bees, add a honey super without an excluder. If you MUST use an excluder, put it on after the bees begin drawing out the foundation in the super, not until. Bees are reluctant to go through an excluder into a super of foundation.
