If possible, you should move her to a secluded area that’s nice and quiet and dark, but has close access to food and water. I had two go broody on 2 May. One is the top hen and the other is at the bottom of the pecking order. The top hen, Goldie, is still sitting in her nest box. The lower ranked hen, Blue, got kicked out of her nest box so often that the eggs died and she lost interest.
I’m lucky in that both of my girls are friendly and never got POed with me. The worst behavior was a little clucking, some puffed up feathers, and touching my hand with her beak. No hissing, no pecking, no drama Mamas!
