I have a 8 white ducks. About two weeks ago one came home with a pretty bad limp. I have babied her along. She will go with the others for a litle while but she knows she can't keep up and will come back home. A couple of days ago I noticed that the leg was swollen ( in the joint and above ) and when I caught her, it felt hot. I have given antibiotics (pill form) to chickens and shots (with LA200) to cattle but have never given a shot to any of my feathered friends. I have seen the LA200 work miracles and I know it would help her. I just don't know what size needle to use or where to give the injection. I can probably figure the dosage. Anybody familiar with Ducks...Help!
