It is becoming more likely that my chicken has gapeworm (the antibiotics don't seem to be working - she does not seem either better or worse) and the suggested remedy is Ivermectin. I am having trouble finding this in stores or online. Is it possible that anyone in the Richmond VA area would have some I could buy or borrow or that anyone can tell me where I can get it? I have found the medicine for other species but was told not to use it unless it is labeled for chickens. Any comments on this would be appreciated Thanks!!
