3 week old duckling suspected splayed leg. Hobbles but will still put weight on the leg, when sat down leg is pushed behind the body and never under the body. Initially suspected a niacin deficiency but 2 weeks on supplements and no real improvement, finally attempted to splint the leg however she now can’t seem to walk at all? She’s pushing both her legs behind her and can’t get back up from there. Don’t want her to injur herself any more and the banding isnt covering her knees. Is this a normal reaction to banding? Has only been on for a couple of hours but she wont move.
