My ducklings went out at 3 weeks old. They were fine even in 45 degree night temps. They slept in the outter perimiter of the heat lamp and did fine. I think so long as they are draft free and have access to warm temps from the heat lamp they will be fine.
This is where mine were kept outside...I covered the sides with boards at night.
