Can my chicks and ducks stay out overnight now?

[BucksBoo]

My pekin ducks are 3 weeks old and my mixed chicks are 4 weeks old today. I’ve been bringing them all out now for a week just during the day. Can they start staying out overnight now? I’m posting pics of them, there shelter and our temps. We live in Alabama. There is a heat lamp on each side, one for ducks and one for chicks. They all have plenty of food and water.

You should be fine, another two weeks ducks and chickens won’t need s lamp at all.
