She raises her neck feathers if you stick your hand in the box and tries to bite your fingers off. (I recommend heavy duty gloves when dealing with her if you must.) If you take her off the nest, for some reason, she'll immediately lay down like she still has eggs (I've only done this at night when my fingers have a better chance of survival.)
I don't recommend moving hens with eggs. I had a Buff Orp that had managed to cram herself into a nest meant for bantam hens and tried to move her. She seemed to accept it, then went back the next morning. I had 50% hatch after scrambling to put them back. The last time I moved her (first batch, lower nest so they didn't kill themselves falling three feet at three hours), she accepted it.
