It might be better if you could have the bullies out of sight, at least at first, but caging them in the run should be better than leaving them loose in the run.
If the bullies are caged inside the run, she will probably figure out that she can safely eat and drink, and they cannot get to her. Of course it may take her a few hours or longer to realize this, given how long it took her to realize they were locked out.
If she can move freely around the run while the bullies are locked up, that will probably be helpful overall. Both she and the bullies will get used to her moving around, within sight of the bullies but not attacked by them. At the moment, it sounds like she and the bullies think she should stay completely out of their sight.
