Given my bald duck problems have been looking at tonics to help them recover quicker from the moult. Claims to be a bit of a panacea in the recent review in Practical poultry (a useful poultry gift, I have ducks and everyone I know gavew me duck pressies for Christmas. I have Mummy rubber ducks, glow-in-the-dark rubber ducks, flashing rubber ducks, vibrating rubber ducks, wooden ducks, soap ducks.......). Anyone have an opinion good or bad or is it just a waste of money?
