Ducklings can take a while to hatch. I would wait it out. Also some moms will leave the nest for a while each day and you can take the opportunity to candle the eggs and get rid of any bad ones. Hope they start hatching soon!
I would like to know the most potent preparation too. Also, are there any preparations which you find decrease the potency. And since elderberry is useful for several ailments, are there certain preparations recommended for particular situations?
