I have a Khaki Campbell duckling that hatched this morning that is "stargazing" and walking backwards. I read that this is a niacin deficiency when it occurs in ducklings? Would this be due to poor nutrition in the parent birds? (these eggs were bought from a breeder). Will a drop or two of baby vits fix this? It is obviously not eating yet but I have specialist duck and goose crumbles for them so should it get better once it starts eating? Thanks.
