Can anyone tell me what they think my birds have? I lost a pheasant to something that the vet couldn't identify, just said that it was dying from liver failure and put it down. Now I've got a juvenile peacock and a hen, in a different part of the yard, that might be suffering from the same thing: weakness, thin, unable to walk. They eat fine, poop appears normal color but runny. I have been treating the peacock with oxytetracyline, not really doing anything. Should I treat them for worms?
