Hello and welcome to Binky Bunny! Thank you for rescuing the bunny. It sounds like it was an easy rescue and that she really wanted to be saved. She was likely deliberately put out by her owners. It unfortunately happens far too often. People either don’t know or don’t care that a domestic rabbit can’t make it outside on its own.
If you haven’t already done so, it would be a good idea to take her to a rabbit savvy vet to be checked out. Here is the vet list page from the Colorado HRS chapter: https://coloradohrs.org/vet-list/. It’s a few years old, but hopefully still pretty much current. It says on the previous page that they recommend the vets with an asterisk by their name.
There is a lot of good information on rabbit care here. Click the BUNNY INFO link at the top of the page.
One of the forum leaders here, LBJ10, is known as the Bunny Name Master. There are other members who might help you with her name too.
