My duck went lame a few months ago and after supplementing her diet with niacin she is starting to get use back in her leg. Now, however, she has a huge abscess on her joint. I do not have a vet anywhere near my area to take her too so I would appreciate suggestions on how to treat this. I'm wondering if lancing it and draining the area and then applying ointment and wrapping it would be a good plan. Thanks so much!
