I doubt it is something that you are doing wrong.
If you can live with the gates and the ex pen, that sounds like a good solution. If she is out with the others, keep her on a leash attached to you. That way she can only go as far as the leash will allow, and I wouldn't use a leash over 6ft, and if it's clipped to you, it's right there for you to grab quickly and correct her.
Good luck with her.
