I'm so sorry this is happening. I don't have much experience with this beyond my ow experience with my duck growing up. The duck lived quite a long time with the condition. It might help if you could try to get a video to share with us, but if the problem is a neurological one, I'm not sure how much we can do. If it were us, we'd probably take him to our vet, but we have a really wonderful, knowledgeable avian vet. Maybe @Isaac 0 will have additional thoughts. Either way, please keep us posted, and don't hesitate to reach out even if you just want to talk. I think most of know how helpless it can feel when one of our ducks appears unwell. We're rooting for him and you!
