Sorry I'm late to respond. Yes like @Miss Lydia said I had the same problem with my Pekin. I now give a daily 'treat' of cut up cherry tomatoes, with the B complex and calcium - she is different duck. She went from not being able to walk and constantly stumbling over things to running around FAST. Also she has so much more energy and talks constantly to me - which I now realize she just didn't feel good for the first year of her life. So sad - but I do think the B complex and calcium is the way to go. Wishing you the best of luck with your Pekin - keep us posted on the progress.
