I can't remember what the oral dose is for 1% Ivermec for an adult peahen; she weighs about 10 lbs. She has face lice. She will eat out of my hand, so I can put it in a treat. I'd like to treat all three of them, though I don't see evidence of lice on the other two they probably do have them. But the other two won't eat out of my hand, so I'd have to toss it to them. If one steals a medicine laced treat from another, and gets a double dose, will they overdose? We have another adult female, about ten pounds, and a juvenile male, probably about 7 or 8 pounds. Those two are the ones that won't eat out of my hand.
