Couldn't ask for better than that. It can work pretty fast. Yes it's a miracle for many ducklings/ducks that have this deficiency.Is it supposed to work that fast? I gave it to her yesterday afternoon, this morning she is much better. How often do I give it?
I'd give her 1 ml morning and another in the evening till you see marked improvement then cut back to 1 ml they really can't OD because what the body can't use the just pee out. Please keep us posted.
