HELP 3 WEEK OLD PEKIN DUCKLING ATTACKED BY SMALL ANIMA:L

[ZiaNiazi]

Yesterday around 8am my pekin duckling wandered off into the corner of my backyard and a small creature must have attacked him. I'm not sure what it is but it gave my duckling 2 flesh wounds both on its chest. Im treating it as best as I possibly can. I have him in the house with a towel for him to lay on and i used some gauze and medical tape for his wounds and have been giving him lots of water and food but hes not been eating much. Every time i get near him to give him water he tries to bite me. His legs are bruised so he can barely walk. I really don't know what to do and I'm not sure if he'll make it.
