Yea unfortunately there’s no way for me to do that with out being very not gentle lol he whips his head around like crazy.When giving oral meds I have had good luck with crouching down with the duck between my knees, back to me, so they can't back up. Then gently holding the beak and opening it, holding the tongue down and slowly putting the meds down the back side of the mouth. If it's more than 1 ml I usually just do 1 ml a squeeze to make sure she doesn't choke. Short nails are good so you don't scratch your duck.
