I don't see the harm in having a fan in the same room as her, if she really seems to be struggling. The chicks will stay under her if they're cold. But if she seems ok I'd leave it. She'll be able to get up soon enough.
Where is she?
It's hard if they're in a small shed outside and the heat builds up.
