My cochin/leghorn X has been trying broody on for size lately. We do have a roo, and we just hatched one of their chicks in the incubator, so we don't need any more (sigh...I love chicken math, but my hub would kill me! We have 17 right now). I just reach under her and collect her egg as soon as she lays it. After a few hours she decides to get up and off she goes. She doesn't care that I reach under her and is very docile. Some hens get downright evil when they are broody and will try and peck the living daylights out of you, however.
