Infection is what you want to prevent. You really need to clean the scratch and or puncture wound with soap and water. You'll need help so get a family member or friend to help hold her while checking her over and cleaning the scratches, wounds or cuts. It may start bleeding again but that will be a good thing. Now dry her really well and put Neosporin or 3 in 1 ointment (both are a topical ointment) on the abrasions. Keep her warm dry and calm at least over the next 24 hours for a minimum. Good luck and keep us posted. One more thing now that the raccoon has the taste of your chickens, be sure and eliminate the possibility of it coming back and finishing the job. Remember relocation of the raccoon only gives someone else the problem.
