on my home and there he was sitting in the road. practically no feathers on his back nor tail. two fifty-cent piece size pieces of skin missing from back and in one of those a puncture wound. legs and wings appear to be ok other than missing feathers. he's shaking from what I can only presume is shock. I've brought him in and put him in the spare bathroom with heat lamp on and some water. in such a hurry to get here to ask before work didn't have time to more fully check him out. I don't know what's safe to use on chickens in the form of medications/disinfectant/cleaners so I've come to the experts here.
