Heat source for ducklings in the summer?

[NimsHouseGarden]

I have six 3 week old runner ducks and they are quickly outgrowing their brooder. I'm considering moving them to their pen, but I don't have an outlet for a heat plate. I'm in North Carolina and we are seeing temperatures in the '90s during the day and 70s during the night. Would they be okay?

My ducks stop using heat by 3 weeks
They aren’t like chicks where they need as much
They should be just fine

Thanks! I moved them off heat and they are doing great! Already getting their feathers.
