So very sorry for your birds. These stories break my heart and they're reported on BYC every day. I will never have dogs while I have chickens because I would worry endlessly about a possible breach. Price way too high for the poor birds - a horrific way to die. For those who have managed to do so without incident, I pray it will always be that way for you and your birds.
For your lone survivor, quickly try to get 1 drop Rescue Remedy in her water changed out at least daily. It may help with the stress. Electrolytes are also often recommended for shock after trauma but it sounds like time has passed. You are likely already keeping her warm and in a cozy stress free place and giving lots of TLC. Did she get puncture wounds - is she on antbiotic? Hope she'll be okay.
