I’m really struggling to find immediate release niacin. I bought some from Holland and Barrett but I think they’re the timed release type, can I still give my ducks that? I’ve noticed one of my runners has developed shaky legs sometimes so I’m putting brewers yeast on their food but I’d like to find some suitable niacin too! Any suggestions from my fellow UK duck parents would be appreciated
