I use bread to give a pill of glucosomine to my old drake works great.One of my ducks is on Metacam (liquid meds) long-term and I just put it on a tiny piece of bread. She gobbles it right down. Very simple and easy. Bread isn't good for ducks in large amount, but one tiny piece (just big enough to soak up the meds) a day is not going to hurt anything at all.
