Chicken got tail feathers plucked out by a hawk, how to treat

[Crowblossom]

Hello,
I have a 2 year old Golden Sex Link chicken (her name is Cinnamon) who got attacked by a hawk not too long ago. I've never had a hawk attack before.
A handful of Cinnamon's tail feathers were plucked out. This is the only injury on her. I checked her injury. There is obvious blood, some skin scratches but they aren't deep. I sprayed chicken medicine on it. It also deters my other chicken from pecking at it while it heals.
Do I need to bathe Cinnamon to clean the scratches or anything? or keep Cinnamon in a separate spot? I currently have two chickens, sadly the others died of illness. I don't want to leave my other chicken alone since the loneliness probably won't help with the shock.
Along with that, will my chickens heal from their shock? They refused to move from inside the coop and will only eat their favorite treats, raisins and sunflower seeds.

Always treat for shock with electrolytes and a little extra sugar in the water. Always wash wounds with soap and water immediately after the injury occurred. Always keep an antibacterial ointment or spray on the wound to counteract bacterial growth in the raw wound.

No need to segregate the injured chicken unless the others are injuring the wound.
