Hmm. Sounds like she has been through Hell.

If she was tied up for 3 months, she might have been eating those jumbos to catch back up.
She needs some stability for sure. How did they keep her? Was she in glass or cage where she could see out? Maybe she is stressed a bit inside of a tub.

I have a Ball python that I rehabbed, kinda did the same thing. She was under fed. She would eat like crazy and once she put some weight back on, went off feed for a bit.

I'm by no means an expert on snakes. Maybe someone else will have a better idea of what would help.
I know my male loves chicks. I would also check out some forums that are more Carpet related.

She might just need more time.
