The poop color sounds familiar after serious injury. It would be good for her to get some probiotics soon. But I don't think it is necessarily the antibiotcs. Not sure. At this point she is probably beginning to feel the injuries, with shock wearing off.
Give her what she will eat for now. Check in with the vet as soon as you can.
I would continue gentle application of saline solution and topical antibiotic around the wound site....
