Normally I'm very optimistic when it comes to wounds in chickens because they can indeed heal from some shocking injuries, however based on what I can make out on the leg picture your girl has lost a lot of the skin on her leg/thigh. That's a really hard place to heal as it's so bendy and mobile. If you are going to try and have it stitched up by a vet do so NOW!
The longer you wait the harder it will be to have stitched up and the more the skin edges start to dry out.
I'm not able to make out much on the other picture but it looks like skin is gone from her side as well. Maybe more injuries further in?
Make sure to keep her warm as that is a lot of wound exposure without the skin to hold in body heat.
Think of it like this- based on her size, and your size, how much skin would you say you'd need to injure/lose on your thigh and/or abdomen to replicate what happened to her? This is an exercise to help you get a handle on the severity of the injury.
I'd say if you try to treat this yourself it will need lots of bandages for frequent changes, if not stitched up, to keep the thigh and/or side muscles protected while new skin granulates in, which takes a while. I really think this is an emergency and she needs to see a vet.
