Sounds like she is going into "feeding mode". Perhaps the more nutritious meals have set off a feeding frenzy (well, not frenzy..but you know what I mean, she wants MORE)
Could be that the additional hides and such are making her feel safer and "bolder" and she is hungry. Have you tried to get her out in the evening ? Or mornings/during daytime? When mine are in their "hungry months" they can be in feed mode every night, as soon as 3 days after a feeding. They will WAIT, ready to go, every evening.
If I need to handle them in the evening and while they are "primed" I just have to let them know that its not feeding time. No rats coming. I usually tap them on the head with a empty paper towel roll or something like that. GENTLY !!!! This is in no way a aggressive touch, this is just a tab, to snap them out of feed mode. As soon as I gently tap or move their head down, they know no food is coming, turn away and I can pick them up no problem.
However, it could also be that all the changes are stressing her out. Since she is still eating well, though, I wonder if she doesn't simply want more.
Can you shoot a short film on how you approach her and what she does ? Her body language?
Have her temps or humidity changed AT ALL ?
Why do you "force" her out for a meal, do you grab her and put her in another enclosure ?
