Does the duckling need a lid to sleep in the carton?

Duck sleeping cartons generally don't need a lid. Ducklings are covered with fluff and usually have enough thermoregulation ability to keep warm. Moreover, covered objects may restrict their activities, which is not conducive to their free activities. So under normal circumstances, ducklings don't need to be covered when sleeping in cartons.
