Do you guys think I should put a metal cage in the coop for her and the babies? With their own food and water for a few days? If I do, should I keep it closed all the time (set up like a mini coop with bedding, etc) or should I open it during the day like I do the regular coop?
I agree with Audio51. I moved by broody - nest, eggs and all - into a large dog crate and gave her separate food/water. She and her chicks are now segregated to one end of the main coop, where they can see and hear everyone else, but aren't bothered by the others.
