Hello, I have a 10 week old Pekin duck that has had a tough start.... First Niacin deficiency within the first 2 weeks of hatching, we caught that and got back on the right track. Then 3 weeks ago fell and broke its knee and that was confirmed by x-ray at the vet. 3 weeks of light swimming and mostly rest its still unable to walk, let alone try to stand and seemingly just depressed. I care for the duck around the clock and its with me at all times. Any advice on depression? Still unsure if he'll ever be able to walk again. Any input would be greatly appreciated.
