She has one of those plastic bins you can use as a brooder. It's in the very first pic.You can use a moist q-tip or soft cloth to try and remove some of the clotted blood around the wound so you can see it better. Do you have someone that can help you with her. You're going to be hard pressed to get a bandage on her head. Just keep the wound from drying out with a triple antibiotic ointment. Do you have a dog or cat crate that you can keep her in inside? I would not put her back in with the others unless they cannot get to her. Keep her warm and dry and the wound from drying out, she will probably be fine.
