I would never underfeed on purpose (unless they were overweight), it was just a theoretical question.
Besides, she goes off food anyway for several months each year so it's better if she has some fat storage for that.
Although if for some reason she doesn't keep eating over the next few months, then that might stop her reproducing next year, or like with the boa you obtained it could cause complications if she did make eggs.
Rest assured, I will try to get her back to around 3000g, and if she wants eggs again then so be it.
She has been staying in the hide box a bit more the last few days, so her behaviour is getting a bit more normal.
But I guess with the glass front covered up the whole vivarium itself is like a hidebox so it's not unexpected for her to be outside of the hidebox more if that makes sense.
Thanks
