Duck-duck-chicken!
It’s very possible that it began as niacin deficiency and other problems came along for the ride, don’t beat yourself up at all.I looked into slipped tendon a few weeks ago but didn’t think it was that because it hadn’t progressed to this point yet and still looked much like Niacin deficiency. I’m now looking into slipped tendon and am thinking that it’s very much possible. He still eats and drinks plenty but he walks much less than the others so you’re likely right about him not getting enough for proper growth. With times being so hard at the moment with the virus I wanted to do what I could on my own with niacin supplementation and avoid the vet if possible, but now that i’m seeing the vet is my only option I wish I had just gone at the start :/ then again it looked so much like Niacin deficiency that if the vet didn’t have an expertise with ducks they may have thought the same


I do feel that not every “avian” vet is the right choice for poultry, either. If you have one that you like and it’s worked for you, awesome. I know personally in my area I definitely would not bring my birds to either of them that are here, as they don’t seem to understand that they are different than caged birds in many ways. Ideally you would have a food animal veterinarian that knows and treats poultry (and don’t just recommend to cull) but those are few and far between. Lol.
