Thats another story I have giving the pox treatment, I don't pull any feathers, I jab them with a homemade 5 needle combo. the mix is to get in the blood from where the feather is pulled, so most here just jab with a needle that was dipped in the Bottle. I take 5 needles and stick them through a pencil erascer and tape the ends together for a handle. Dip in the bottle and Jab the bird just to the side of the breast bone this make 5 holes for the mix to enter the bird and gets a great take and you can feel the scab when it forms each time you handle the bird.
