I have a 8-9 wk pekin duckling.At 3 days she couldnt walk.With a lot of TLC she can walk,sometimes run,she tries to preen her belly but falls backward.Her spine is hunched and curved.She doesnt seem to be in any pain.Has anyone ever heard of a duck living a good life with these problems.I am worried about when she starts to lay.will she beable to with no problems?She is about 4x smaller than her sisters.I have some mallards thats same age they are the same size as her if not a little bigger.
