Hello, my 7 month old pekin has an injury on her wing. Im not sure how she got it. She isnt injured anywhere else that I can tell. I've cleaned it with betadine and put tripple antibiotic ointment on it. Cut away feathers it looks like she's missing feathers for about two inches down on her left wing. I brought her in the house. She's in a warm darkness room. Should I give her amoxacilin? I have human kind and I have fish amoxacilin. She weighs 12.40 pounds. Any advice would be appreciated thanks.
