Our nearly 6 year old Pekin Drake has been limping for about 2 weeks now. Our first thought was that he simply strained his leg but now I'm suspecting there is a larger issue. He is eating and pooping normally however it seems like his behavior has changed. He is not interacting as his usual self around the other ducks and then I noticed that his abdomen seemed larger and after feeling it I'm certain that its not normal. His abdomen feels hard and I'm wondering if the limp is to compensate for the pain or swelling in the abdomen. He will be taken to the vet tomorrow and I'm generally concerned. Has anyone else experienced these same symptoms with a drake?
