I gave my Limpy the charcoal , and all the other medication as capsules orally: Grab duck, ignore protest, open bill, ignore protest, slide down pill into the ducks throat on the top left side of the duck's mouth so that it cannot go down the wrong way. Stuff it down ½ finger, then you both get a good drink. Don't forget to count
your fingers after that action!
Limpy started Friday afternoon with his right leg being limp, then both legs were paralyzed on Saturday and on Sunday i thought he would die, because he wasn't eating or drinking. Monday morning he was better, started to drink and gulped down food by the hand-full. It took him several weeks to recover and he still has a limp in his right leg, but otherwise is doing fine. Good luck!
