@Miss Lydia is pretty amazing in my book!Is there any chance she could have gotten into anything...toxic? Any, oil from your car...any old ..junk that would leave a residue...anything you could think of that a duck could stick their beak in? Two of my ducks got into an old sink that had som bad insulation and junk...unfortunately it had toxins...they needed activated charcoal....that is good to have on hand for ducks, or any animal, really, to try to eliminate toxins. Otherwise I would definitely try the BComplex..they sell it At TS...in the cattle section..you can put 1 ml one a yummy treat, like meal worms, or peas, or something you know she’ll eat...it’s better than putting it in water, because then you know she’s getting it all. The vit will help to perk her up for sure, and then give her immune system a boost to fight whatever this is,..until you can find out.. @Miss Lydia is our resident expert on duck everything....she’ll be along to read this soon!!![]()
