If your eggs will be doing a staggered hatch because they were laid over a couple of days your hen and the first hatchlings won't move from the nest the first day to two days, so your goal should be to get her to a safe area on ground level. I'm not able to view the web cam, but from your description it sounds like you could create a space on the floor for her and create a chicken wire barrier to help her decide to stay put. I was able to open the crate up after a couple of days and the other hens and even papa Morty would go in to visit. ..but Lee let them all know not to mess with her. Once you get her situated I bet you'll come home and find her still on the nest with just a couple of little heads peeking out from under a wing.
